| * tx25: fix linker file for newer ld supportAlbert Aribaud2010-11-17-21/+19
| | | | | | | | | | | | | | | | | | older ld emitted all ELF relocations in input sections named .rel.dyn, whereas newer ld uses names of the form .rel*. The linker script only collected .rel.dyn input sections. Rewrite to collect all .rel* input sections. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr>
* | powerpc/85xx: add CONFIG_SYS_TEXT_BASE_SPL for 85xx nand spl buildHaiying Wang2010-11-12-6/+6
|/ | | | | | | | | | Introduce a SPL specific CONFIG_SYS_TEXT_BASE_SPL define to be used by the linker. This has similiar semantics to CONFIG_SYS_TEXT_BASE however since SPL is a unqiue image we introduce a new variable to control its text base address.

* 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>

* ppc4xx: Big header cleanup, mostly PPC440 relatedStefan Roese2010-09-23-1/+1
| | | | | | | | | | | This patch starts a bit PPC4xx header cleanup. First patch mostly touches PPC440 files. A later patch will touch the PPC405 files as well.

* nand_boot_fsl_nfc.c: make "nfc" a "static const" pointerHeiko Schocher2010-09-19-5/+1
| | | | | | | | | | | | | With -fPIC enabled, this variable needs an entry in the GOT, which causes the image size to exceed 2 KiB which is the maximum allowed for some systems.

* 83xx/85xx/86xx: LBC register cleanupBecky Bruce2010-07-16-5/+4
| | | | | | | | | | | | | | | | | | | | | 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.

Since the main makefile builds nand_spl/board/$(BOARDDIR) (which makes sense), and the board Makefile and linker script are the only two necessary files to enable out-of-tree building, and other boards have duplicated nand makefiles (e.g. 8536ds & 8569mds), it only seems prudent to copy these two files in the name of the 8315 too.

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>

* ppc4xx: Canyonlands-NAND-boot: Support 2 Crucial 512MByte SODIMM'sStefan Roese2009-07-30-14/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Tested with those SODIMM's: CT6464AC667.8FB (dual ranked) CT6464AC667.4FE (single ranked) Signed-off-by: Stefan Roese <sr@denx.de>

* 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>

| | | | | | | | | | | | 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.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
