Using optimized versions of memset and memcpy from linux brings a quite
noticeable speed (x2 or better) improvement for these two functions.
Here are some numbers for test done with jadecpu
| HEAD(1)| HEAD(1)| HEAD(2)| HEAD(2)|
| | +patch | | +patch |
---------------------------+--------+--------+--------+--------+
Reset to prompt | 438ms | 330ms | 228ms | 120ms |
| | | | |
TFTP a 3MB img | 4782ms | 3428ms | 3245ms | 2820ms |
| | | | |
FATLOAD USB a 3MB img* | 8515ms | 8510ms | ------ | ------ |
| | | | |
BOOTM LZO img in RAM | 3473ms | 3168ms | 592ms | 592ms |
where CRC is | 615ms | 615ms | 54ms | 54ms |
uncompress | 2460ms | 2462ms | 450ms | 451ms |
final boot_elf | 376ms | 68ms | 65ms | 65ms |

BOOTM LZO img in FLASH | 3207ms | 2902ms | 1050ms | 1050ms |
where CRC is | 600ms | 600ms | 135ms | 135ms |
uncompress | 2209ms | 2211ms | 828ms | 828ms |
| | | | |
Copy 1.4MB from NOR to RAM | 134ms | 72ms | 120ms | 70ms |
(1) No dcache
(2) dcache enabled in board_init
*Does not work when dcache is on
