| Hi, |
| |
| so this is the port to the Embedded Planet RPX Super Board. |
| |
| ATTENTION |
| This code is only tested on the AY-Version, which is an early release with some |
| hardware bugs. The main problem is that this board uses the default Hard Reset |
| Configuration Word and not the 4 bytes located at start of FLASH because at |
| 0xFE000000 is no FLASH. The FLASH consists out of 4 chips each 16bits wide. Be |
| carefull, the bytes are swapped. So DQ0-7 is the high byte, DQ8-15 ist the low |
| byte. |
| |
| The icache can only manually be enabled after reset. |
| The FLASH and main SDRAM is working with icache enabled. |
| The local SDRAM can only be used as data memory when icache is enabled. |
| If U-Boot runs in local SDRAM, TFTP does not work. |
| The functions in mii_phy.c are all working. Call mii_phy_discover() out of |
| eth_init() and solve the linker error. |
| I2C, RTC/NVRAM and PCMCIA are not working yet. |
| |
| TODO |
| The 32MB local SDRAM is working but not shown in the startup messages of |
| U-Boot. If you locate U-Boot or any other program to this area it won't run. |
| Turning the ichache off does not solve this problem. |
| |
| As I won't buy another RPX Super there might be some little work to do for you |
| getting this U-Boot port running on the final board. |
