2009-08-21ARM: compiler options cleanup - improve tool chain supportWolfgang Denk
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.

2009-08-09mxc-mmc: sdhc host driver for MX2 and MX3 proccessorIlya Yanok
This is a port of Linux driver for SDHC host controller hardware found on Freescale's MX2 and MX3 processors. Uses new generic MMC framework (CONFIG_GENERIC_MMC) and it looks like there are some problems with a framework (at least on LE cpus). Some of these problems are addressed in the following patches.

2009-07-27Make include/common.h usable by assembler codeWolfgang Denk
Commit 70ebf316 factored out the ROUND() macro into include/common.h, not realizing that the primary use of this macro on AT91 systems was in start.S where common.h was not included, and could not be included because it contains a lot of C code which the assembler doesn't understand. This patch wraps such code in common.h in a "#ifndef __ASSEMBLY__" construct, and then adds an include to cpu/arm926ejs/start.S thus solving the problem. Signed-off-by: Wolfgang Denk <wd@denx.de>

2009-07-06arm nomadik: use 1000 as HZ value and rewrite timer codeAlessandro Rubini
This sets CONFIG_SYS_HZ to 1000 as required, and completely rewrites timer code, which is now both correct and much smaller. Unused functions like udelay_masked() have been removed as no driver uses them, even the ones that are not currently active for this board. mtu.h is copied literally from the kernel sources.

2009-06-12arm: timer and interrupt init reworkJean-Christophe PLAGNIOL-VILLARD

2009-06-12davinci: add basic dm355/dm350/dm335 supportDavid Brownell
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>
2009-06-12davinci: fix dm644x bugletsDavid Brownell

2009-06-12davinci: split out some dm644x-specific bits from pscDavid Brownell
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>
2009-06-12davinci: cpu-specific build uses conditional make syntaxDavid Brownell
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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-06-12davinci: move psc support board-->cpuDavid Brownell

2009-06-12DaVinci now respects SKIP_LOWLEVEL_INITDavid Brownell
