| * | arc: significant cache rework | Alexey Brodkin | 2015-07-01 | 1 | -9/+1 |
| | | | | | | | | | | | | | | | | | | | [1] Align cache management functions to those in Linux kernel. I.e.: a) Use the same functions for all cache ops (D$ Inv/Flush) b) Split cache ops in 3 sub-functions: "before", "lineloop" and "after". That way we may re-use "before" and "after" functions for region and full cache ops. [2] Implement full-functional L2 (SLC) management. Before SLC was simply disabled early on boot. It's also possible to enable or disable L2 cache from config utility. [3] Disable/enable corresponding caches early on boot. So if U-Boot is configured to use caches they will be used at all times (this is useful in partucular for speed-up of relocation). Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> | ||||
| * | arc: clean-up init procedure | Alexey Brodkin | 2015-04-03 | 1 | -0/+25 |
| Intention behind this work was elimination of as much assembly-written code as it is possible. In case of ARC we already have relocation fix-up implemented in C so why don't we use C for U-Boot copying, .bss zeroing etc. It turned out x86 uses pretty similar approach so we re-used parts of code in "board_f.c" initially implemented for x86. Now assembly usage during init is limited to stack- and frame-pointer setup before and after relocation.
