* 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.

| * allow MCF532x to use CONFIG_MONITOR_IS_IN_RAMWolfgang Wegner2010-03-04-0/+7
| | | | | | | | | | | | | | | | | | | | | | CONFIG_MONITOR_IS_IN_RAM is broken for MCF532x. This patch fixes this by conditionally - removing the vector table at the beginning of code - not overwriting the vector base register - removing the code to re-set the PLL, which effectively disables SDRAM access Signed-off-by: Wolfgang Wegner <w.wegner@astro-kom.de>
| * MCF5271-only: Added a weak board_reset function to allow custom resetRichard Retanubun2010-03-04-0/+39
| | | | | | | | | | | | | | | | | | | | | | This patch adds a board_reset function to allow boards to specify their own custom reset sequence (e.g. resetting by timing out watchdog). Tested only on MCF5271, can be expanded if needed.

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