2011-07-29powerpc/85xx: provide 85xx flush_icache for cmd_cacheMatthew McClintock
This provides a function that will override the weak function flush_icache to let 85xx boards to flush the icache cc: Kumar Gala <kumar.gala@freescale.com> Signed-off-by: Matthew McClintock <msm@freescale.com>
2011-07-28unify version_stringAndreas Bießmann
This patch removes the architecture specific implementation of version_string where possible. Some architectures use a special place and therefore we provide U_BOOT_VERSION_STRING definition and a common weak symbol version_string.

2011-04-20Revert "PowerPC: Add support for -msingle-pic-base"Wolfgang Denk
This reverts commit 39768f7715ed637ef02f49fc7de664cc1aaf14b3. Reson: it breaks a number of boards with embedded environment as the code size grows in some places.
2011-04-11PowerPC: Add support for -msingle-pic-baseJoakim Tjernlund
-msingle-pic-base is a new gcc option for ppc and it reduces the size of my u-boot with 6-8 KB. While at it, add -fno-jump-tables too to save a few more bytes. -msingle-pic-base will be in gcc 4.6, however backported patches are available at http://bugs.gentoo.org/show_bug.cgi?id=347281 Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
2011-03-27rename _end to __bss_end__Po-Yu Chuang
Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang <ratbert@faraday-tech.com>
2011-01-14powerpc/85xx: Fix bug in dcache_disableKumar Gala
We set the L1 dache register with a bogus register value. Need to be using 'r3' instead of 'r0'. Reported-by: John Traill <john.traill@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-11-14PowerPC: Don't destroy fixup table while doing fixupsJoakim Tjernlund
The fixup procedure just stored a constant value in the fixup table rather than just adjusting the table. Although that doesn't seem to do any harm, it prevents relocation more that once. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
2010-11-11powerpc/85xx: rename CONFIG_SYS_TEXT_BASE to CONFIG_SYS_MONITOR_BASEHaiying Wang
Use CONFIG_SYS_MONITOR_BASE instead of CONFIG_SYS_TEXT_BASE in early init code so we can share the same code with NAND or NOR boot and not have additional ifdefs in here. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-10-26Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk
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.

2010-10-18powerpc: do not fixup NULL ptrsJoakim Tjernlund
The fixup routine must not fixup NULL pointers. Problem can be seen by char *testfun(void) __attribute__((weak)); char *(*myfun)(void) = testfun; Then add printf("myfun:%p, &myfun:%p\n", myfun, &myfun); before relocation and after relocation. myfun should be NULL in both cases but it is not.

2010-10-18Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk
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.

2010-10-12powerpc: Remove warm reset entry pointPeter Tyser
No boards utilize the warm reset entry point, so remove it. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2010-07-26powerpc/85xx: Move INIT_RAM_ADDR physical address to 36-bit spaceyork
If 36-bit physical address is used, move the INIT_RAM_ADDR to higher address. This frees the low 4GB address space for better use. Signed-off-by: York Sun <yorksun@freescale.com>
2010-04-21Move arch/ppc to arch/powerpcStefan Roese
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
