arm: Remove OMAP2420H4 and all omap24xx support

2013-06-10T12:43:19Z

The omap2420H4 was the only mainline omap24xx board. Prior to being fixed by Jon Hunter in time for v2013.04 it had been functionally broken for a very long time. Remove this board as there's not been interest in it in U-Boot for quite a long time. Signed-off-by: Tom Rini

arm: do not force d-cache enable on all boards

2011-09-04T09:36:16Z

c2dd0d45540397704de9b13287417d21049d34c6 added dcache_enable() to board_init_r(). This enables d-cache for all ARM boards. As a result some of the arm boards that are not cache-ready are broken. Revert this change and allow platform code to take the decision on d-cache enabling. Also add some documentation for cache usage in ARM. Signed-off-by: Aneesh V

arm: minor fixes for cache and mmu handling

2011-07-04T08:55:25Z

1. make sure that page table setup is not done multiple times 2. flush_dcache_all() is more appropriate while disabling cache than a range flush on the entire memory(flush_cache()) Provide a default implementation for flush_dcache_all() for backward compatibility and to avoid build issues.

ARMV7: Fix build for non-OMAP3 boards

2010-11-04T19:27:02Z

Commit c3d3a54 uses CONFIG_ARMV7 to determine whether to call the v7_flush_cache_all function. This breaks the build for all non-OMAP3 boards (like Panda and OMAP4430SDP) since there is only a v7_flush_cache_all implementation for OMAP3. This patch uses CONFIG_OMAP3XXX instead of CONFIG_ARMV7 so that only boards with a v7_flush_cache_all will make the call. Tested on Beagle, Overo, Panda, and OMAP4430SDP Signed-off-by: Steve Sakoman Signed-off-by: Sandeep Paulraj

ARM (ARM11): add data cache support, test on Qong board

2010-09-19T17:29:51Z

Add data cache support for arm1136 systems. Enable "cache" command on Qong board and test performance. Test 1: Loading 127 MB of data from NAND flash into RAM: Instr. Cache off on on Data Cache off off on -------------------------------------------------- QONG (ARM11) 177s 95s 43s = x 4.1 Test 2: uncompressing a gzipped image from RAM to RAM (size compressed: 6.5 MiB, uncompressed: 35 MiB): Instr. Cache off on on Data Cache off off on -------------------------------------------------- QONG (ARM11) 1.54s 0.95s 0.18s = x 8.6 Portions of this work were supported by funding from the CE Linux Forum.

ARM V7 (OMAP): add data cache support, test on Beagle board

2010-09-19T17:29:51Z

Add data cache support for ARM V7 systems. Used cache flush functions from linux:arch/arm/mm/cache-v7.S developed from Catalin Marinas. Enable "cache" command on Beagle board and test performance. Test 1: Loading 127 MB of data from NAND flash into RAM: Instr. Cache off on on Data Cache off off on -------------------------------------------------- Beagle (Cortex A8) 116s 106s 30.3s = x 3.8 Test 2: uncompressing a gzipped image from RAM to RAM (size compressed: 6.5 MiB, uncompressed: 35 MiB): Instr. Cache off on on Data Cache off off on -------------------------------------------------- Beagle (Cortex A8) 1.84s 1.64s 0.12s = x 15.3 Portions of this work were supported by funding from the CE Linux Forum.
