Hello.
I have some old DSL-2500 devices BRU_C revision, BCM6332, 8Mb ram, 2Mb spi flash NXW25P16, 96332CG_F4W board id. I have idea use it as a network gpio box with openwrt. And have some problems.
I temporally solder 32Mb ram for testing and build current trunk BARRIER BREAKER (Bleeding Edge, r40569), ramdisk image, netboot it and get message:

1. board_prom_init doesn't detect CFE version, board_bcm963xx: CFE version: unknown
i made some research and add before CFE version detect in board_bcm963xx.c:
cfe = boot_addr + BCM963XX_CFE_VERSION_OFFSET;
printk(KERN_INFO PFX "%x %x %x %x %x %x %x %x - %x %x %x %x %x %x %x %x\n", cfe[0], cfe[1], cfe[2], cfe[3], cfe[4], cfe[5], cfe[6], cfe[7], cfe[8], cfe[9], cfe[10], cfe[11], cfe[12], cfe[13], cfe[14], cfe[15]);output: board_bcm963xx: 63 65 76 00 76 00 0c 00 0c 00 00 00 00 00 00 00
but must be: 00000570: 63 66 65 2d 76 01 00 25 0c 01 00 00 00 00 00 00
so it reads every first byte of 16 bit word and i have no idea why.
2. spi flash is not detected, more in log

I have some skills in C programming, so if someone help me with right direction i can myself test it.
Sorry for language, english is not my native.
