* IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic2011-04-27-4/+0
| | | | | | | | | | As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h). This requires several nasty #ifdef in the drivers to include the correct header. The patch cleans up the driver and renames the header files as for the other i.MX processors.

* nand_spl: Fix large page nand_command()Alex Waterman2011-04-15-0/+4
| | | | | | | | | | This patch changes the large page nand_command() routine to use a word offset instead of a byte offset. The 'offs' argument gets divided by 2 so that the offset passed to nand_command() is still by byte offset. Originally, the offset was not shifted and when too high an offset was requested the nand chip would attempt to read non-existent data. Signed-off-by: Alex Waterman <awaterman@dawning.com>

| | | | | | | | | | | | | | | commit 8aba9dceebb14144e07d19593111ee3a999c37fc Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS breaks the usage of --gc-section to build nand_spl. We still need linker option --gc-section for every uboot image, not only the main one. LDFLAGS_FINAL passes the --gc-sections to each uboot image. To get the proper linker flags, we use LDFLAGS and LDFLAGS_FINAL to replace PLATFORM_LDFLAGS in the Makefile of each nand_spl board.

* powerpc/nand spl: link libgccScott Wood2010-12-16-8/+8
| | | | | | | | | | | | | | | | Recent GCC (4.4+) performs out-of-line epilogues in some cases, when optimizing for size. It causes a link error for _restgpr_30_x (and similar) if libgcc is not linked. It actually increases size with very small binaries, due to the fixed size of the out-of-line code, and not having any functions that actually need to restore more than 2 or 3 registers. But I don't see a way to turn it off, other than asking GCC to optimize for speed -- which may also increase size for some boards.

* Add board support for hawkboardSughosh Ganu2010-11-30-0/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds basic board support for TI's OMAP-L138 based Hawkboard. This board is pretty similar to the da850 EVM. Support for nand and network access is added in this version. The following bootup procedure is used. At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand controllers and copies the second stage bootloader(nand_spl) to RAM. The secondary bootloader then copies u-boot from a predefined location in the nand flash to the RAM, and passes control to the u-boot image. Three config options are supported * hawkboard_config - Used to create the u-boot.bin. Tftp the u-boot.bin image to the RAM from u-boot, and flash to the nand flash at address 0xe0000. * hawkboard_nand_config - Used to generate the secondary bootloader(nand_spl) image. This creates an elf file u-boot-spl under nand_spl/. Create an AIS signed image using this file, and flash it to the nand flash at address 0x20000. The ais file should fit in one block. * hawkboard_uart_config - This is same as the first image, but with the TEXT_BASE as expected by the RBL(0xc1080000).

* 83xx: Fix NAND_SPL link addressScott Wood2010-11-27-6/+6
| | | | | | | | | | | | | | | | | 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.

* Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk2010-10-29-2/+2
| | | | | | | | | | | | | | | | When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>

| | | | | | | | | | | This patch starts a bit PPC4xx header cleanup. First patch mostly touches PPC440 files. A later patch will touch the PPC405 files as well.

| | | | | | | | | | | | | | | | | | | | | Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.
