      cm5200: fix FAT function prototypes · 26f8a4ac
      Stephen Warren authored
      Remove FAT function prototypes from the cm5200 firmware update code, and
      include the relevant headers instead.
      
      This exposes the fact that the custom prototyoe for do_fat_read() in
      this file was incorrect. Rather than simply fixing the call-site, replace
      do_fat_read() with fat_exists(). This removes the only use of
      do_fat_read() outside of the FAT code.

      fdt: Allow ft_board_setup() to report failure · e895a4b0
      Simon Glass authored
      This function can fail if the device tree runs out of space. Rather than
      silently booting with an incomplete device tree, allow the failure to be
      detected.
      
      Unfortunately this involves changing a lot of places in the code. I have
      not changed behvaiour to return an error where one is not currently
      returned, to avoid unexpected breakage.
      
      Eventually it would be nice to allow boards to register functions to be
      called to update the device tree. This would avoid all the many functions
      to do this. However it's not clear yet if this should be done using driver
      model or with a linker list. This work is left for later.

      MAINTAINERS: comment out blank M: field · 535aad29
      Masahiro Yamada authored
      Since commit ddaf5c8f
      (patman: RunPipe() should not pipe stdout/stderr unless asked),
      Patman spits lots of "Invalid MAINTAINERS address: '-'"
      error messages for patches with global changes.
      It takes too long for Patman to process them.
      
      Anyway, "M:    -" does not carry any important information.
      Rather, it is just like a place holder in case of assigning
      a new board maintainer.  Let's comment out.
      
      This commit can be reproduced by the following command:
      
      find . -name MAINTAINERS | xargs sed -i -e '/^M:[[:blank:]]*-$/s/^/#/'

      Add board MAINTAINERS files · 93d4334f
      Masahiro Yamada authored
      We have switched to Kconfig and the boards.cfg file is going to
      be removed. We have to retrieve the board status and maintainers
      information from it.
      
      The MAINTAINERS format as in Linux Kernel would be nice
      because we can crib the scripts/get_maintainer.pl script.
      
      After some discussion, we chose to put a MAINTAINERS file under each
      board directory, not the top-level one because we want to collect
      relevant information for a board into a single place.
      
      TODO:
      Modify get_maintainer.pl to scan multiple MAINTAINERS files.

      kconfig: add board Kconfig and defconfig files · dd84058d
      Masahiro Yamada authored
      This commit adds:
       - arch/${ARCH}/Kconfig
          provide a menu to select target boards
       - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
          set CONFIG macros to the appropriate values for each board
       - configs/${TARGET_BOARD}_defconfig
          default setting of each board
      
      (This commit was automatically generated by a conversion script
      based on boards.cfg)
      
      In Linux Kernel, defconfig files are located under
      arch/${ARCH}/configs/ directory.
      It works in Linux Kernel since ARCH is always given from the
      command line for cross compile.
      
      But in U-Boot, ARCH is not given from the command line.
      Which means we cannot know ARCH until the board configuration is done.
      That is why all the "*_defconfig" files should be gathered into a
      single directory ./configs/.

      Handle most LDSCRIPT setting centrally · 83b7e2a7
      Scott Wood authored
      Currently, some linker scripts are found by common code in config.mk.
      Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
      sometimes in arch config.mk and sometimes in board config.mk.  Some
      are found using an arch-specific rule for looking in CPUDIR, etc.
      
      Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
      when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
      that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.
      
      Replace all of this -- except for a handful of boards that are actually
      selecting a linker script in a unique way -- with centralized ldscript
      finding.
      
      If board code specifies LDSCRIPT, that will be used.
      Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.
      
      If neither of these are specified, then the central config.mk will
      check for the existence of the following, in order:
      
      $(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
      $(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
      $(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
      $(TOPDIR)/$(CPUDIR)/u-boot.lds
      
      Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
      were dead code, because they were overridden by a CPUDIR u-boot.lds under
      the old powerpc rules.  These boards' own u-boot.lds have bitrotted and
      no longer work -- these lds files have been removed.

      Switch from archive libraries to partial linking · 6d8962e8
      Sebastien Carlier authored
      Before this commit, weak symbols were not overridden by non-weak symbols
      found in archive libraries when linking with recent versions of
      binutils.  As stated in the System V ABI, "the link editor does not
      extract archive members to resolve undefined weak symbols".
      
      This commit changes all Makefiles to use partial linking (ld -r) instead
      of creating library archives, which forces all symbols to participate in
      linking, allowing non-weak symbols to override weak symbols as intended.
      This approach is also used by Linux, from which the gmake function
      cmd_link_o_target (defined in config.mk and used in all Makefiles) is
      inspired.
      
      The name of each former library archive is preserved except for
      extensions which change from ".a" to ".o".  This commit updates
      references accordingly where needed, in particular in some linker
      scripts.
      
      This commit reveals board configurations that exclude some features but
      include source files that depend these disabled features in the build,
      resulting in undefined symbols.  Known such cases include:
      - disabling CMD_NET but not CMD_NFS;
      - enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

      Make sure that argv[] argument pointers are not modified. · 54841ab5
      Wolfgang Denk authored
      The hush shell dynamically allocates (and re-allocates) memory for the
      argument strings in the "char *argv[]" argument vector passed to
      commands.  Any code that modifies these pointers will cause serious
      corruption of the malloc data structures and crash U-Boot, so make
      sure the compiler can check that no such modifications are being done
      by changing the code into "char * const argv[]".
      
      This modification is the result of debugging a strange crash caused
      after adding a new command, which used the following argument
      processing code which has been working perfectly fine in all Unix
      systems since version 6 - but not so in U-Boot:
      
      int main (int argc, char **argv)
      {
      	while (--argc > 0 && **++argv == '-') {
      /* ====> */	while (*++*argv) {
      			switch (**argv) {
      			case 'd':
      				debug++;
      				break;
      			...
      			default:
      				usage ();
      			}
      		}
      	}
      	...
      }
      
      The line marked "====>" will corrupt the malloc data structures and
      usually cause U-Boot to crash when the next command gets executed by
      the shell.  With the modification, the compiler will prevent this with
      an
      	error: increment of read-only location '*argv'
      
      N.B.: The code above can be trivially rewritten like this:
      
      	while (--argc > 0 && **++argv == '-') {
      		char *arg = *argv;
      		while (*++arg) {
      			switch (*arg) {
      			...

      POST: Remove duplicated post_hotkey_pressed() functions · 39ff7d5f
      Stefan Roese authored
      This patch introduces a weak default function for post_hotkey_pressed(),
      returning 0, for boards without hotkey support. The long-running tests
      won't be started on those boards. This default function was implemented
      in many board directories. By implementing this weak default we can
      remove all those duplicate versions.
      
      Boards with hotkey support, can override this weak default function
      by defining one in their board specific code.

      General help message cleanup · a89c33db
      Wolfgang Denk authored
      Many of the help messages were not really helpful; for example, many
      commands that take no arguments would not print a correct synopsis
      line, but "No additional help available." which is not exactly wrong,
      but not helpful either.
      
      Commit ``Make "usage" messages more helpful.'' changed this
      partially. But it also became clear that lots of "Usage" and "Help"
      messages (fields "usage" and "help" in struct cmd_tbl_s respective)
      were actually redundant.
      
      This patch cleans this up - for example:
      
      Before:
      	=> help dtt
      	dtt - Digital Thermometer and Thermostat
      
      	Usage:
      	dtt         - Read temperature from digital thermometer and thermostat.
      
      After:
      	=> help dtt

      Fix all linker script to handle all rodata sections · f62fb999
      Trent Piepho authored
      A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
      which needs to be added the the linker script.  Instead of just adding this
      one section, we use a wildcard ".rodata*" to get all rodata linker section
      gcc has now and might add in the future.
      
      However, '*(.rodata*)' by itself will result in sub-optimal section
      ordering.  The sections will be sorted by object file, which causes extra
      padding between the unaligned rodata.str.1.1 of one object file and the
      aligned rodata of the next object file.  This is easy to fix by using the
      SORT_BY_ALIGNMENT command.
      
      This patch has not be tested one most of the boards modified.  Some boards
      have a linker script that looks something like this:
      
      *(.text)
      . = ALIGN(16);
      *(.rodata)
      *(.rodata.str1.4)
      *(.eh_frame)
      
      I change this to:
      
      *(.text)
      . = ALIGN(16);
      *(.eh_frame)
      *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
      
      This means the start of rodata will no longer be 16 bytes aligned.
      However, the boundary between text and rodata/eh_frame is still aligned to
      16 bytes, which is what I think the real purpose of the ALIGN call is.

      Change initdram() return type to phys_size_t · 9973e3c6
      Becky Bruce authored
      This patch changes the return type of initdram() from long int to phys_size_t.
      This is required for a couple of reasons: long int limits the amount of dram
      to 2GB, and u-boot in general is moving over to phys_size_t to represent the
      size of physical memory.  phys_size_t is defined as an unsigned long on almost
      all current platforms.
      
      This patch *only* changes the return type of the initdram function (in
      include/common.h, as well as in each board's implementation of initdram).  It
      does not actually modify the code inside the function on any of the platforms;
      platforms which wish to support more than 2GB of DRAM will need to modify
      their initdram() function code.
      
      Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
      MPC8641HPCN.
