* ARM: relocation: don't undef CONFIG_SYS_ARM_WITHOUT_RELOCBen Gardiner2010-10-13-1/+0
| | | | | | | | | There were some #undef's of CONFIG_SYS_ARM_WITHOUT_RELOC added to a few board configs as part of the arm relocation series; but these are not needed now as we do not #undef what is not #defined in the first place.

* ARM: implement relocation for ARM926Heiko Schocher2010-09-19-0/+5
| | | | | | | | | | | | | | | | | | | | | Change the implementation for arm926 to relocate the code to an arbitrary address in RAM. Adapt the TX25 (i.MX25), magnesium board to test the changes. On the tx25 board TEXT_BASE is set to the final relocation address to prevent one more copying of u-boot code when relocating.

* ARM (ARM926ejs): add data cache support, tested on magnesium and tx25 boardHeiko Schocher2010-09-19-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable "cache" command on tx25 and magnesium 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 -------------------------------------------------- magnesium 32,6s 22,5s 30s = x 1,09 tx25 (29MB only) 9,69s 5,05s 8,16s = x 1,19 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 -------------------------------------------------- magnesium 4,25s 2,08s 1,72s = x 2,47 tx25 4,82s 2,04s 1,84s = x 2,62 Portions of this work were supported by funding from the CE Linux Forum.

* arm, i.mx27: add support for magnesium board from projectiondesignHeiko Schocher2010-04-30-0/+237
This patch adds support for the magnesium board from projectiondesign. This board uses i.MX27 SoC and has 8MB NOR flash, 128MB NAND flash, FEC ethernet controller integrated into i.MX27. As this port is based on the imx27lite port, common config options are collected in include/configs/imx27lite-common.h Signed-off-by: Heiko Schocher <hs@denx.de>
