* 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.

* 83xx: Fix NAND_SPL link addressScott Wood2010-11-27-30/+55
| | | | | | | | | | | | | | | | | Apply the same fix for 83xx as was done for 85xx in commit 96196a1f7546904563994d2d041804a816d7c139. Without this, NAND SPLs are built with the text base intended for the main image, resulting in a broken, very large u-boot-nand.bin. The block of defines for NAND boot is moved closer to where CONFIG_SYS_TEXT_BASE is defined. We can't directly use CONFIG_SYS_NAND_U_BOOT_DST in the definition of CONFIG_SYS_TEXT_BASE because autoconf.mk will include the literal text "CONFIG_SYS_NAND_U_BOOT_DST", but at least keep them close and point out that they're supposed to be the same.

* arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings workWolfgang Denk2010-11-26-50/+20
| | | | | | | | | | | | | | | | | | | | | | | | | As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. 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.

* WINBOND_83C553: enable only on boards that actually use it.Wolfgang Denk2010-11-26-4/+4
| | | | | | | | | | | | | | | | | | | | So far, only the BAB7xx board would call the initialise_w83c553f() function for the WINBOND 83C553 chip, even though some other boards (HIDDEN_DRAGON, Sandpoint8240, Sandpoint8245) enabled it in their board configuration. 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.

The maximum clock the chip can support can only be determined from the label on the package (not software readable). Introduce a method to pass the maximum allowed clock rate information to kernel using ATAG_REVISION. The kernel uses this information to determine the maximum cpu clock rate reachable using cpufreq. Note that U-Boot itself does not set the CPU clock rate. The CPU clock is setup by a primary bootloader ("UBL").
