* ARM: compiler options cleanup - improve tool chain supportWolfgang Denk2009-08-21-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some time there have been repeated reports about build problems with some ARM (cross) tool chains. Especially issues about (in)compatibility with the tool chain provided runtime support library libgcc.a caused to add and support a private implementation of such runtime support code in U-Boot. A closer look at the code indicated that some of these issues are actually home-made. This patch attempts to clean up some of the most obvious problems and make building of U-Boot with different tool chains easier: - Even though all ARM systems basicy used the same compiler options to select a specific ABI from the tool chain, the code for this was distributed over all cpu/*/config.mk files. We move this one level up into lib_arm/config.mk instead. - So far, we only checked if "-mapcs-32" was supported by the tool chain; if yes, this was used, if not, "-mabi=apcs-gnu" was selected, no matter if the tool chain actually understood this option. There was no support for EABI conformant tool chains. This patch implements the following logic: 1) If the tool chain supports "-mabi=aapcs-linux -mno-thumb-interwork" we use these options (EABI conformant tool chain). 2) Otherwise, we check first if "-mapcs-32" is supported, and then check for "-mabi=apcs-gnu" If one test succeeds, we use the first found option. 3) In case 2), we also test if "-mno-thumb-interwork", and use this if the test succeeds. [For "-mabi=aapcs-linux" we set "-mno-thumb-interwork" mandatorily.] This way we use a similar logic for the compile options as the Linux kernel does. - Some EABI conformant tool chains cause external references to utility functions like raise(); such functions are provided in the new file lib_arm/eabi_compat.c Note that lib_arm/config.mk gets parsed several times, so we must make sure to add eabi_compat.o only once to the linker list.

* davinci: add basic dm355/dm350/dm335 supportDavid Brownell2009-06-12-0/+46
| | | | | | | | | | | | | Add some basic declarations for DaVinci DM355/DM350/DM335 support, keyed on CONFIG_SOC_DM355. (DM35X isn't quite right because the DM357 is very different; while the DM355 is like a DM355 without the MPEG/JPEG coprocessor). These have different peripherals than the DM6446, and some of the peripherals are at different addresses. Notably for U-Boot, there's no EMAC, and the NAND controller address is different Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* davinci: split out some dm644x-specific bits from pscDavid Brownell2009-06-12-75/+123
| | | | | | | | | | | | | | Split out DaVinci DM6446-specific bits from more generic bits: - Add a CONFIG_SOC_DM644X. All current boards use DM6446 chips; DM6443 and DM6441 chips differ in available peripherals. - Move most DM644X-specific bits from psc.c to a new dm644x.c file, which is conditionally built. It provides device-specific setup. Plus minor coding style and comment updates with respect to the PSC. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* davinci: cpu-specific build uses conditional make syntaxDavid Brownell2009-06-12-3/+5
| | | | | | | | | | | Update cpu/arm926ejs/davinci/Makefile to use COBJ-y type syntax. Add the first conditional: for EMAC driver support. Not all chips have an EMAC; and boards might not use it, anyway. This doesn't touch PHY configuration; that should eventually become conditional too.

| * ARM DaVinci: Fix broken HW ECC for large page NAND.Hugo Villeneuve2008-09-10-5/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on original patch by Bernard Blackham <bernard@largestprime.net> U-boot's HW ECC support for large page NAND on Davinci is completely broken. Some kernels, such as the 2.6.10 one supported by MontaVista for DaVinci, rely upon this broken behaviour as they share the same code for ECCs. In the existing scheme, error detection *might* work on large page, but error correction definitely does not. Small page ECC correction works, but the format is not compatible with the mainline git kernel. This patch adds ECC code that matches what is currently in the Davinci git repository (since NAND support was added in 2.6.24). This makes the ECC and OOB layout written by u-boot compatible with Linux for both small page and large page devices and fixes ECC correction for large page devices. The old behaviour can be restored by defining the macro CFG_DAVINCI_BROKEN_ECC, which is undefined by default.

| | | | | | | | | | DM644x is just one of a series of DaVinci chips that use the EMAC driver. By replacing all the function names that start with dm644x_* to davinci_* we make these function more portable. I have tested this change on my EVM.

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-18/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial.

| | | | | | | | | | | | | | | | | | | | | | | | | Fix ARM based DaVinci DM644x timer overflow handling and cleanup timer code. Changes: - Remove *_masked() functions as noted by Wolfgang - Adapt register naming to recent TI spec (sprue26, March 2007) - Fix reset_timer() handling - As reported by Pieter [1] the overflow fix introduced a delay of factor 16 (e.g 2 seconds became 32). While the overflow fix is basically okay, it missed to divide udelay by 16, too. Fix this. [1] http://article.gmane.org/gmane.comp.boot-loaders.u-boot/38179 - Remove software division of timer count value (DIV(x) macro) and do it in hardware (TIM_CLK_DIV).
