2010-10-07mpc8569mds: fix consuming long time while relocating code.Haiying Wang
The original code maps boot flash as non-cacheable region. When calling relocate_code in flash to copy u-boot from flash to ddr, every loop copy command is read from flash. The flash read speed will be the bottleneck, which consuming long time to do this operation. To resovle this, map the boot flash as write-through cache via tlb. And set tlb to remap the flash after code executing in ddr, to confirm flash erase operation properly done.

2010-10-07mpc8569mds: fix CONFIG_ENV_SIZEHaiying Wang
CONFIG_ENV_SIZE of MPC8569MDS was wrongly set to CONFIG_ENV_SECT_SIZE which is 128KB, so it took longer time to do crc32 calculation for ENV than it should do. It causes the bootup for MPC8569MDS significantly slow. This patch fixs it to 0x2000(8KB), also fix the comment for CONFIG_ENV_SECT_SIZE to correct size.

2010-10-07x86: Implement fully relocatable imageGraeme Russ
u-boot.bin can be loaded at any 4-byte aligned memory location and directly 'jumped' to using the 'go' command using the load address as the start address. Doing so performs a 'warm boot' which skips memory initialisation and other low-level initialisations, relocates U-Boot to upper memory and starts U-Boot in RAM as per normal 'cold boot'
2010-10-07x86: Use loops instead of memcpy/memset in board_init_fGraeme Russ
Provides a small speed increase and prepares for fully relocatable image. Downside is the TEXT_BASE, bss, load address etc must ALL be aligned on a a 4-byte boundary which is not such a terrible restriction as everything is already 4-byte aligned anyway
2010-10-07x86: Rearrange linker scriptGraeme Russ
Tidy up the linker script and discard some sections to save space
2010-10-07x86: Rename linker script symbolsGraeme Russ
Create more generic names for the symbols exported from the linker script
2010-10-07x86: Set cold/warm boot flagGraeme Russ
2010-10-07x86: Place global data below stack before entering CGraeme Russ
By reserving space for the Global Data immediately below the stack during assembly level initialisation, the C declaration of the static global data can be removed, along with the 'RAM Bootstrap' function. This results in cleaner code, and the ability to pass boot-up flags from assembler into C
2010-10-07x86: Dont clobber %eax after getting memory sizeGraeme Russ
By using another register, reduce code size by one instruction
2010-10-07x86: Don't clobber %ebxGraeme Russ
%ebx will hold low-level boot flags and must be preserved
2010-10-07x86: Remove usage of %ebp as a return pointerGraeme Russ
Using %ebp as a return pointer prevents creating 'load anywhere' images
2010-10-07x86: Move ECC initialisation outside RAM initialisationGraeme Russ
To allow for 'load anywhere' images, the %ebp return pointer 'hack' must be removed, so we cannot have two 'calls' to get_mem_size
2010-10-07x86: Remove progress indication in low-level initGraeme Russ
Progress indication is not relocation friendly so remove it in preperation for full relocatability support
2010-10-07x86: Fix %ss and %esp in register structure for interruptsGraeme Russ
2010-10-07x86: Change compiler optionsGraeme Russ
Change to: - reparam=3 - no-from-pointer - no-stack-protector - preferred-stack-boundary=2 - no-top-level-reorder These options make the code a little smaller and faster
2010-10-07x86: Coding Style CleanupGraeme Russ
Perform some basic code cleanups of the x86 files
2010-10-07x86: Move loading of GTD to C codeGraeme Russ
Linux has C macros and code to load the GTD after switching to Protected Mode. Using these greatly simplifies the assembler code
2010-10-07x86: use gc sections to reduce image sizeGraeme Russ
Follow the discussion of Charles Manning and Mike Frysinger. Using gc_sections helps reduce image size.
2010-10-07x86: zboot updateGraeme Russ
The header of recent Linux Kernels includes the size of the image, and therefore is not needed to be passed to zboot. Still process the third parameter (size of image) in the event that an older kernel is being loaded
2010-10-07x86: Use TEXT_BASE in linker scriptsGraeme Russ
Use TEXT_BASE rather than a hard-coded base address on x86 linker scripts. This will allow any board to define its base link address without having to modify the linker script
2010-10-07x86: Make CONFIG_RELOC_FIXUP_WORKS generic for all x86 boardsGraeme Russ
Relocation is not board-specific for the x86 architectrure, so CONFIG_RELOC_FIXUP_WORKS can be defined globally in the config.h
2010-10-07x86: Remove bi_env from do_bdinfoGraeme Russ
Commit 55e97429d1e6cf0976711e4e0f29ea924b7e5917 removed the definition from /arch/i386/include/asm/u-boot.h but not its usage in do_bdinfo()

2010-10-06sf: spansion: fixing erasing when sector size >64KiBMarc-André Hébert
The spansion_erase currently only works when the sector size is 64KB. cmd[1] should contain the higher 8 bit of the 24 bit address of the sector to be erased. Currently it is holding the sector index to be erased which happens to be the same thing when the sector size is 64KB.

2010-10-06include/compiler.h: remove uint typedef for __MACH__Andreas Bießmann

2010-10-06lib/hashtable.c: add CONFIG_ENV_MIN_ENTRIESAndreas Bießmann
This patch adds a new config parameter for adjusting the calculation of hash table size when importing a buffer. When importing a extremely small buffer (e.g. the default_environment) the old calculation generated a hash table which could hold at most the buffer content but no more entires. The new calculation add a fixed number of entries to the result to fit better for small import buffers. This amount may be configured by the user in board file to adjust the behaviour.

2010-10-06cmd_elf: add an option for loading ELFs according to PHDRsMike Frysinger
The current ELF loading function does a lot of work above and beyond a simple "loading". It ignores the real load addresses and loads things into their virtual (runtime) address. This is undesirable when we just want it to load an ELF and let the ELF do the actual C runtime init. So add a command line option to let people choose to load via either the program or section headers. I'd prefer to have program header loading be the default, but this would break historical behavior, so I'll leave section header loading as the norm. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-10-06rules.mk: make sure we always create a .depend fileWolfgang Denk
There are some cases where "make depend" would always run when entering a directory. This happened when both the $(SRCS) and $(HOSTSRCS) lists were empty (which is for example typical for the examples/api/ directory). Avoid this by making sure that a ".depend" file gets always created, even if empty. Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>

2010-10-04ppc4xx: Use common ns16550 functions in 4xx UART POST driverStefan Roese
This patch changes the PPC4xx POST UART driver to use the common NS16550 functions for receiving and sending. Additionally the local function for SoC divisor setup are removed. Instead the functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This removes code duplication. Also the common CONFIG_SYS_NS16550_COMx defines are now used to describe the POST UART's. And a compile breakage is fixed, introduced by a git merge of the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to "asm/ppc4xx.h". Fixed as well with this patch.
