      Consolidate bool type · 472d5460
      York Sun authored
      'bool' is defined in random places. This patch consolidates them into a
      single header file include/linux/types.h, using stdbool.h introduced in C99.
      
      All other #define, typedef and enum are removed. They are all consistent with
      true = 1, false = 0.
      
      Replace FALSE, False with false. Replace TRUE, True with true.
      Skip *.py, *.php, lib/* files.

      Replace __bss_end__ with __bss_end · 3929fb0a
      Simon Glass authored
      Note this is a tree-wide change affecting multiple architectures.
      
      At present we use __bss_start, but mostly __bss_end__. This seems
      inconsistent and in a number of places __bss_end is used instead.
      
      Change to use __bss_end for the BSS end symbol throughout U-Boot. This
      makes it possible to use the asm-generic/sections.h file on all
      archs.

      Refactor linker-generated arrays · ef123c52
      Albert ARIBAUD authored
      Refactor linker-generated array code so that symbols
      which were previously linker-generated are now compiler-
      generated. This causes relocation records of type
      R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
      code which uses LGA able to run before relocation as
      well as after.
      
      Note: this affects more than ARM targets, as linker-
      lists span possibly all target architectures, notably
      PowerPC.

      common: Discard the __u_boot_cmd section · 8b493a52
      Marek Vasut authored
      The command declaration now uses the new LG-array method to generate
      list of commands. Thus the __u_boot_cmd section is now superseded and
      redundant and therefore can be removed. Also, remove externed symbols
      associated with this section from include/command.h .

      Fix incorrect use of getenv() before relocation · f0c0b3a9
      Wolfgang Denk authored
      A large number of boards incorrectly used getenv() in their board init
      code running before relocation.  In some cases this caused U-Boot to
      hang when certain environment variables grew too long.
      Fix the code to use getenv_r().

      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.

      Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value · 25ddd1fb
      Wolfgang Denk authored
      CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
      being able to use "sizeof(struct global_data)" in assembler files.
      Recent experience has shown that manual synchronization is not
      reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
      GENERATED_GBL_DATA_SIZE which gets automatically generated by the
      asm-offsets tool.  In the result, all definitions of this value can be
      deleted from the board config files.  We have to make sure that all
      files that reference such data include the new <asm-offsets.h> file.
      
      No other changes have been done yet, but it is obvious that similar
      changes / simplifications can be done for other, related macro
      definitions as well.

      Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE · 14d0a02a
      Wolfgang Denk authored
      The change is currently needed to be able to remove the board
      configuration scripting from the top level Makefile and replace it by
      a simple, table driven script.
      
      Moving this configuration setting into the "CONFIG_*" name space is
      also desirable because it is needed if we ever should move forward to
      a Kconfig driven configuration system.

      ppc4xx: Use common NS16550 driver for PPC4xx UART · 550650dd
      Stefan Roese authored
      This patch removes the PPC4xx UART driver. Instead the common NS16550
      driver is used, since all PPC4xx SoC's use this peripheral device.
      
      The file 4xx_uart.c now only implements the UART clock calculation
      function which also sets the SoC internal UART divisors.
      
      All PPC4xx board config headers are changed to use this common NS16550
      driver now.

      ppc4xx: Big header cleanup part 2, mostly PPC405 related · afabb498
      Stefan Roese authored
      This cleanup is done by creating header files for all SoC versions and
      moving the SoC specific defines into these special headers. This way the
      common header ppc405.h and ppc440.h can be cleaned up finally.
      
      As a part from this cleanup, the GPIO definitions for PPC405EP are
      corrected. The high and low parts of the registers (for example
      CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in
      the wrong order. This patch now fixes this issue by switching these
      xxxH and xxxL values. This brings the GPIO 405EP port in sync with all
      other PPC4xx ports.

      ppc4xx/fdt/flash: Change fdt_fixup_nor_flash_node() to not rely on cs size · 8a805df1
      Stefan Roese authored
      This patch changes the behaviour of the fdt_fixup_nor_flash_node()
      function. Now it doesn't patch the size of the "reg" property with the
      chip-select size, but with the size returned from the new function
      flash_get_bank_size(). This function will return per weak default the
      flash size of the bank (bank = chip-select numer) detected by the flash
      driver. If this does not fit your needs, this function may be overridden
      by a board specific one.
      
      For this the parameters needed to be changed. So I intentionally squashed
      the PPC4xx stuff using this routine into this patch. Otherwise it would
      not be git-bisectable anymore.
      
      The board specific function for the AMCC/APM Ebony eval board is now
      included in this patch version.

      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) {
