* tegra: usb: move implementation into right directoryLucas Stach2013-03-147-560/+536
| | | | | | | | | | | | | | | | This moves the Tegra USB implementation into the drivers/usb/host directory. Note that this merges the old /arch/arm/cpu/armv7/tegra20/usb.c file into ehci-tegra.c. No code changes, just moving stuff around. v2: While at it also move some defines and the usb.h header file to make usb driver usable for Tegra30. NOTE: A lot more work is required to properly init the PHYs and PLL_U on Tegra30, this is just to make porting easier and it does no harm here.

* tegra: usb: make controller init functions more self containedLucas Stach2013-03-141-12/+12
| | | | | | | | | | | | | There is no need to pass around all those parameters. The init functions are able to easily extract all the needed setup info on their own. This allows to move out the controller init into ehci_hcd_init later on, without having to save away global state for later use and thus bloating the file global state.

* Refactor linker-generated arraysAlbert ARIBAUD2013-03-12177-351/+380
| | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

| | | | | | | | | | | | | Turn __bss_start and __bss_end__ from linker-generated to compiler-generated symbols, causing relocations for these symbols to change type, from R_ARM_ABS32 to R_ARM_RELATIVE. This should have no functional impact, as it affects references to __bss_start and __bss_end__ only before relocation, and no such references are done.

* Remove linker lists (LGAs) from SPL linker scriptsAlbert ARIBAUD2013-03-1212-42/+164
| | | | | | | | | | | | Many SPL linker scripts needlessly include linker lists (aka LGAs). Remove them whenever possible; keep it only in the seven am335x_evm variants (am335x_evm, am335x_evm_uart[1-5], am335x_evm_spiboot), where there is actual content in output section .u_boot_list.

* arm: omap: map u_boot_lists section to .sramAlbert ARIBAUD2013-03-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Output section .u_boot_list was left unmapped in u-boot-spl.lds for omap-common, causing the location counter to roll back to bteween .rodata and .data, making __image_copy_end and _end symbols wrong. Mapping output section .u_boot_list to memory .sram fixes these symbols' mapping. This modifies the SPL binary but has no functional impact, as __image_copy_end and _end are never used in SPLs and u_boot_list is empty for all 29 boards affected (omap4_sdp4430 eco5pk igep0030 am335x_evm_uart3 omap3_beagle am3517_crane igep0032 mt_ventoux pcm051 am3517_evm omap3_evm_quick_mmc am335x_evm_uart2 am335x_evm_spiboot am335x_evm_uart1 omap3_evm igep0030_nand omap3_overo igep0020 am335x_evm omap4_panda omap5_evm am335x_evm_uart4 devkit8000 tricorder mcx twister omap3_evm_quick_nand am335x_evm_uart5 igep0020_nand).

Also add additional debugging output when enabled. During this investigation, two situations have been seen: 1. calculate_relocation_address(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; turns into 111166f: b8 83 c4 17 01 mov $0x117c483,%eax whih is beyond the end of bss: 0117b484 g .bss 00000000 __bss_end Somehow the __bss_end here is 255 bytes ahead. 2. do_elf_reloc_fixups(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; Here the __text_start is 0 in the file: 1111d9f: bb a0 e0 13 01 mov $0x113e0a0,%ebx 1111da4: 81 ef 00 00 00 00 sub $0x0,%edi As it happens, both of these are in pre-relocation code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The memory layout calculations are done in calculate_relocation_address(), and coreboot has its own version of this function. But in fact all we really need is to set the top of usable RAM, and then the base version will work as is. So instead of allowing the whole calculate_relocation_address() function to be replaced, create board_get_usable_ram_top() which can be used by a board to specify the top of the area where U-Boot relocations to.

Note: For some boards the hash command is not enabled, neither are sha1, sha256 or the verify option. In this case the full hash implementation adds about 500 bytes of overhead. So as a special case, we use #ifdef to select very simple bahaviour in that case. The justification for this is that it is currently a very common case (virtually all boards enable crc32 but only some enable more advanced features). Signed-off-by: Simon Glass <sjg@chromium.org>
