* powerpc: Remove warm reset entry pointPeter Tyser2010-10-12-137/+25
| | | | | | No boards utilize the warm reset entry point, so remove it. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* powerpc: Zero out board info struct on bootupPeter Tyser2010-10-12-16/+1
| | | | | | | This puts the board info struct in a known state and allows the removal of other code which initialized board info fields to 0. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* | davinci_emac: davinci_eth_set_mac_addr to ->write_hwaddrBen Gardiner2010-10-11-20/+0
|/ | | | | | | | | | | | | | | | | | | | | | This patch proposes to migrate the davinci_emac driver to using the eth_device->write_hwaddr function pointer as suggested by Ben Warren. All the davinci boards had the behaviour, prior to this patch, of sync'ing the environment variable enetaddr with the MAC address read from non-volatile storage on boot -- when the two locations disagreed, the environment variable value took precendence. This patch keeps the same behaviour but lets eth_initialize take care of it. This patch refactors davinci_emac setup in the boards so that the MAC address is read from non-volatile storage into the environment variable and then the environment variable value is use in eth_intialize. The only exception is the direct call to davinci_eth_set_mac_addr made by the da830evm board init which was changed into an assignment of the enetaddr field.

| * x86: Implement fully relocatable imageGraeme Russ2010-10-07-24/+35
| | | | | | | | | | | | | | | | 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'
| * x86: Use loops instead of memcpy/memset in board_init_fGraeme Russ2010-10-07-16/+31
| | | | | | | | | | | | | | 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
| * x86: Rearrange linker scriptGraeme Russ2010-10-07-2/+3
| | | | | | | | Tidy up the linker script and discard some sections to save space
| * x86: Rename linker script symbolsGraeme Russ2010-10-07-24/+24
| | | | | | | | Create more generic names for the symbols exported from the linker script
| * x86: Set cold/warm boot flagGraeme Russ2010-10-07-16/+13
| |
| * x86: Place global data below stack before entering CGraeme Russ2010-10-07-37/+37
| | | | | | | | | | | | | | 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
| * x86: Dont clobber %eax after getting memory sizeGraeme Russ2010-10-07-3/+2
| | | | | | | | By using another register, reduce code size by one instruction
| * x86: Don't clobber %ebxGraeme Russ2010-10-07-7/+12
| | | | | | | | %ebx will hold low-level boot flags and must be preserved
| * x86: Remove usage of %ebp as a return pointerGraeme Russ2010-10-07-10/+10
| | | | | | | | Using %ebp as a return pointer prevents creating 'load anywhere' images
| * x86: Move ECC initialisation outside RAM initialisationGraeme Russ2010-10-07-14/+14
| | | | | | | | | | To allow for 'load anywhere' images, the %ebp return pointer 'hack' must be removed, so we cannot have two 'calls' to get_mem_size
| * x86: Remove progress indication in low-level initGraeme Russ2010-10-07-42/+2
| | | | | | | | | | Progress indication is not relocation friendly so remove it in preperation for full relocatability support
| * x86: Fix %ss and %esp in register structure for interruptsGraeme Russ2010-10-07-4/+45
| |
| * x86: Change compiler optionsGraeme Russ2010-10-07-17/+12
| | | | | | | | | | | | | | | | | | | | | | 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
| * x86: Coding Style CleanupGraeme Russ2010-10-07-373/+362
| | | | | | | | Perform some basic code cleanups of the x86 files
| * x86: Move loading of GTD to C codeGraeme Russ2010-10-07-96/+57
| | | | | | | | | | Linux has C macros and code to load the GTD after switching to Protected Mode. Using these greatly simplifies the assembler code
| * x86: use gc sections to reduce image sizeGraeme Russ2010-10-07-0/+3
| | | | | | | | | | Follow the discussion of Charles Manning and Mike Frysinger. Using gc_sections helps reduce image size.
| * x86: zboot updateGraeme Russ2010-10-07-5/+13
| | | | | | | | | | | | 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
| * x86: Make CONFIG_RELOC_FIXUP_WORKS generic for all x86 boardsGraeme Russ2010-10-07-0/+2
| | | | | | | | | | Relocation is not board-specific for the x86 architectrure, so CONFIG_RELOC_FIXUP_WORKS can be defined globally in the config.h

| * | powerpc/85xx: fix rev.2 job queue LIODN error stormKim Phillips2010-10-07-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pumping line-rate traffic though a p4080 rev.2, which is configured to encrypt packets prior to forwarding through an IPsec tunnel, gets this error: of_platform ffe302000.jq: DECO: desc idx 22: LIODN error. DECO was trying to share from itself or from another DECO but the two Non-SEQ LIODN values didn't match or the "shared from" DECO's Descriptor required that the SEQ LIODNs be the same and they aren't. Since high traffic rates cause DECOs to begin to start sharing shared descriptors amongst themselves, and DECOs inherit job queue LIODNs when accessing shared descriptors, and a recently discovered rev.2 h/w erratum requires all sharing job queues in a partition have same liodn assignment, reassign the first job queue's liodn assignment to the rest.

| * Blackfin: propagate target cpu defines when building embedded envMike Frysinger2010-10-02-0/+3
| | | | | | | | | | | | | | | | | | | | | | Since we're no longer extracting the env from the target ELF file (since upstream wouldn't take that change), we're back to the problem of cpu defines not properly propagating to the env setup stage. So the embedded env built by the host compiler doesn't match the one that is linked into the u-boot env. Reported-by: Vivi Li <vivi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
