* Introduce a new linker flag LDFLAGS_FINALHaiying Wang2011-03-22-19/+32
| | | | | | | | | | | | | | | 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>

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.

This image contains two parts: a 4K NAND loader and a main U-Boot image. The former is appended to the latter to produce u-boot-nand.bin. The 4K NAND loader includes the corresponding nand_spl directory, along with the code twisted by CONFIG_NAND_SPL. The main U-Boot image just like a general U-Boot image except the parts that included by CONFIG_SYS_RAMBOOT. When power on, eLBC will automatically load from bank 0 the 4K NAND loader into the FCM buffer RAM where CPU can execute the boot code directly. In the first stage, the NAND loader copies itself to RAM or L2SRAM to free up the FCM buffer RAM, then loads the main image from NAND flash to RAM or L2SRAM and boot from it. This patch implements the NAND loader to load the main image into L2SRAM, so the main image can configure the RAM by using SPD EEPROM. In the first stage, the NAND loader copies itself to the second to last 4K address space, and uses the last 4K address space as the initial RAM for stack. Obviously, the size of L2SRAM shouldn't be less than the size of the image used. If so, the workaround is to generate another image that includes the code to configure the RAM by SPD and load it to L2SRAM first, then relocate the main image to RAM to boot up.

* Fix all linker scripts for older binutils versions (pre-2.16)Wolfgang Denk2009-08-21-18/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f62fb99941c6 fixed handling of all rodata sections by using a wildcard combined with calls to ld's builtin functions SORT_BY_ALIGNMENT() and SORT_BY_NAME(). Unfortunately these functions were only introduced with biunutils version 2.16, so the modification broke building with all tool chains using older binutils. This patch makes it work again. This is done by omitting the use of these functions for such old tool chains. This will result in slightly larger target binaries, as the rodata sections are no longer in optimal order alignment-wise which reauls in unused gaps, but the effect was found to be insignificant - especially compared to the fact that you cannot build U-Boot at all in the current state. As ld seems to have no support for conditionals we run the linker script through the C preprocessor which can be easily used to remove the unwanted function calls. Note that the C preprocessor must be run with the "-ansi" (or a "-std=") option to make sure all the system-specific predefined macros outside the reserved namespace are suppressed. Otherise, cpp might for example substitute "powerpc" to "1", thus corrupting for example "OUTPUT_ARCH(powerpc)" etc. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Canyonlands boards are equipped with different SODIMM's. This is no problem with the "normal" NOR booting Canyonlands U-Boot, since it automatically detects the SODIMM's via SPD data and correctly configures them. But the NAND booting version is different. Here we only have 4k of image size to completely setup the hardware, including DDR2 setup. So we need to use a fixed DDR2 setup here. This doesn't work for different SODIMM's right now. Currently only this Crucial SODIMM is support: CT6464AC667.8FB (dual ranked) Now some boards are shipped with this SODIMM: CT6464AC667.4FE (single ranked) This patch now supports both SODIMM's by configuring first for the dual ranked DIMM. A quick shows, if this module is really installed. If this test fails, the DDR2 controller is re-configured for the single ranked SODIMM.

* nand_spl: Fix cmd_ctrl usage in nand_boot.c.Scott Wood2009-07-07-7/+11
| | | | | | | | | | | | | | | | When adding large page NAND support to this file, I had a misunderstanding about the exact semantics of NAND_CTRL_CHANGE (which isn't documented anywhere I can find) -- it is apparently just a hint to drivers, which aren't required to preserve the old value for subsequent non-"change" invocations. This change makes nand_boot.c no longer assume this. Note that this happened to work by chance with some NAND drivers, which don't preserve the value, but treat 0 equivalently to NAND_CTRL_ALE. I don't have hardware to test this, so any testing is appreciated. Signed-off-by: Scott Wood <scottwood@freescale.com>
* nand_spl: read environment early, when booting from NAND using nand_splGuennadi Liakhovetski2009-07-07-0/+10
| | | | | | | | | | | | Currently, when booting from NAND using nand_spl, in the beginning the default environment is used until later in boot process the dynamic environment is read out. This way environment variables that must be interpreted early, like the baudrate or "silent", cannot be modified dynamically and remain at their default values. Fix this problem by reading out main and redundand (if used) copies of the environment in the nand_spl code.
