      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/.

      SPDX: fix IBM-pibs license identifier · 1b387ef5
      Wolfgang Denk authored
      The SPDX License List version 1.19 now contains an official entry for
      the IBM-pibs license.  However, instead of our suggestion "ibm-pibs",
      the SPDX License List uses "IBM-pibs", with the following rationale:
      "The reason being that all other SPDX License List short identifiers
      tend towards using capital letters unless spelling a word.  I'd prefer
      to be consistent to this end".
      
      Change the license IDs to use the official name.

      SPDX-License-Identifier: convert PIBS licensed files · 46263f2d
      Wolfgang Denk authored
      This commit adapts the files that were derived from PIBS (PowerPC
      Initialization and Boot Software) codeto using SPDX License
      Identifiers.
      
      So far, SPDX has not assigned an official License ID for the PIBS
      license yet, so this should be considered preliminary.
      
      Note that the following files contained incorrect license information:
      
      	arch/powerpc/cpu/ppc4xx/4xx_uart.c
      	arch/powerpc/cpu/ppc4xx/start.S
      	arch/powerpc/include/asm/ppc440.h
      
      These files included, in addition to the GPL-2.0 / ibm-pibs dual
      license as inherited from PIBS, a GPL-2.0+ license header which was
      obviously incorrect.  This has been removed.

      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 .

      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.

      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.

      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) {
      			...

      ppc4xx: Big cleanup of PPC4xx defines · 297a6587
      Stefan Roese authored
      This patch cleans up multiple issues of the 4xx register (mostly
      DCR, SDR, CPR, etc) definitions:
      
      - Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
      - Change the defines to better match the names from the
        user's manuals (e.g. cprpllc -> CPR0_PLLC)
      - Removal of some unused defines
      
      Please test this patch intensive on your PPC4xx platform. Even though
      I tried not to break anything and tested successfully on multiple
      4xx AMCC platforms, testing on custom platforms is recommended.

      Dual-license IBM code contributions · 31773496
      Josh Boyer authored
      It was brought to our attention that U-Boot contains code derived from the
      IBM OpenBIOS source code originally provided with some of the older PowerPC
      4xx development boards.  As a result, the original license of this code has
      been carried in the various files for a number of years in the U-Boot project.
      
      IBM is dual-licensing the IBM code contributions already present in U-Boot
      under either the terms of the GNU General Public License version 2, or the
      original code license already present.

      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.
