* mpc83xx: fix pcie enumerationBaidu Boy2010-12-13-6/+6
| | | | | | | | | | | | This patch fix a problem for the pcie enumeration for mpc83xx cpus. Without this we will not get correct value in hose->regions[...]. The pointer *reg in function mpc83xx_pcie_init_bus() shall not be changed. Because we will use this pointer as a parameter to call function mpc83xx_pcie_register_hose().

* | ARM: make timer variables in gt_t available for all ARM platformsPrafulla Wadaskar2010-12-09-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | All code that attemots to access variables in BSS before relocation (for example directly or indirectly by board_init_f()) needs to be fixed. Especially timer.c needs to fix on most of the ARM platforms. This patch makes timer related variables in gd_t available for all ARM implementations.

* | armv7: fix relocation skipAndreas Bießmann2010-12-09-2/+2
| | | | | | | | | | | | | | | | | | I doubt the stack_setup() was defective before: we load the current location of _start and compare against destination of relocate_code(). If we are already there we shoud skip the relocation and jump over to clear_bss. Before the clear_bss was also skipped. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
* | arm: fixloop(): do not use r8 for relocationAndreas Bießmann2010-12-09-42/+42
| | | | | | | | | | | | | | | | | | r8 is used for global_data and should therefore be left alone! For C code the compiler flag --fixed-r8 does the job, but in assembler we need to be aware of that fact. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

| | | | | | | | | | | | | | | | | | In case we are still at relocation target address before relocation we do not need to load the registers needed for relocation.

* | arm: copy_loop(): use scratch registerAndreas Bießmann2010-12-09-70/+70
| | | | | | | | | | | | | | | | | | This patch uses r1 as scratch register for copy_loop(). Therefore we do not longer need r7 for the storage of relocate_code()'s 'addr_moni' (the destination address of relocation). Therefore r7 can be used later on for other purposes.

One example is on systems that might use a L2 or L3 cache in SRAM mode and initialize that cache from SRAM mode back to being a cache in cpu_init_r. We set this on the 85xx boards that have support for NAND, SPI, or SDHC/MMC boot support as they use a secondary cache in SRAM mode and need the env_addr pointer relocated since we change from SRAM to normal cache mode in cpu_init_r. Also removed CONFIG_SYS_SPL as its not used anywhere. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* | | POWERPC: enable --gc-sections and -ffunction-sections -fdata-sectionsWolfgang Denk2010-11-27-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The switch from archive libraries to partial linking has introduced a number of problems, that are non-trivial to solve. For example, it is no longer possible to include individual object files in the linker script as we did before for example in the case of boards with embedded environment to fill up the gap caused by the need to align the environment on flash erase block boundaries. The best (but unfortunately not easiest) approach to address this problem is to enable -ffunction-sections (and -fdata-sections) so we can again (and even in much finer granularity) place certain code where we want it. When doing this step, it seems only consequent to also add --gc-sections which has the added benefit of reducing the memory footprint of the U-Boot image (both in flash and in RAM). Unfortunately, this requires changes to a lot of linker scripts.

We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.

These boards were also missing other config settings needed for that, which resulted in build errors like this: drivers/pci/libpci.o:(.got2+0x84): undefined reference to `ide_bus_offset' Switch arch/powerpc/lib/board.c to call initialise_w83c553f() not on a per-board base, but when a WINBOND_83C553 in enabled in a configuration (like BAB7xx), and disable it in the boards that had this set so far.
