* OMAP3: workaround for ARM Cortex-A8 erratum 725233Siarhei Siamashka2010-03-07-0/+6
| | | | | | | | | | | | | | | | | | | | | | 725233: PLD instructions executed with PLD data forwarding enabled can result in a processor deadlock This deadlock can happen when NEON load instructions are used together with cache preload instructions (PLD). The problematic conditions can be triggered in-the-wild by NEON optimized functions from pixman library (http://cgit.freedesktop.org/pixman), which perform dynamic adjustment of prefetch distance. The workaround disables PLD data forwarding by setting PLD_FWD bit in L2 Cache Auxiliary Control Register as recommended in ARM Cortex-A8 errata list. The deadlock can only happen on r1pX revisions of Cortex-A8 (used in OMAP34xx/OMAP35xx). Performance impact of the workaround is practically non-existant.

| | | | | | | | | | | | | | | | | | | In function get_osc_clk_speed(), do not change/ update the divider for SYS_CLK as it can has cascading effect on the other derived clocks. Sudden change in divider value can lead to inconsistent behavior in the system - often leading to crashes. The problem was found when working with OMAP3EVM using DM3730 processor card.

* | Generic udelay() with watchdog supportIngo van Lil2009-12-05-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>

* OMAP3 Move cache routine to cache.STom Rix2009-10-13-183/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v7_flush_dcache_all, because it depends on omap ROM code is not generic. Rename the function to 'invalidate_dcache' and move it to the omap cpu directory. Collect the other omap cache routines l2_cache_enable and l2_cache_disable with invalide_dcache into cache.S. This means removing the old cache.c file that contained l2_cache_enable and l2_cache_disable. The conversion from cache.c to cache.S was done most through disassembling the uboot binary. The only significant change was to change the comparision for the return of get_cpu_rev from cmp r0, #0 beq earlier_than_label Which was lost information to cmp r0, #CPU_3XX_ES20 blt earlier_than_label The paths through the enable routine were verified by adding an infinite loop and seeing the hang. Then removing the infinite loop and seeing it continue. The disable routine is similar enough that it was not tested with this method. Run tested by cold booting from nand on beagle and zoom1. Compile tested on MAKEALL arm. Signed-off-by: Tom Rix <Tom.Rix@windriver.com>

* ARM: compiler options cleanup - improve tool chain supportWolfgang Denk2009-08-21-8/+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.

* General help message cleanupWolfgang Denk2009-06-12-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>
