[ECOS] Re[ECOS] dboot + Flash driver for 2k page size

[lux_cnis]

Hi all,

I am a newbie in ecos. I am working to reboot my arm board TS-7250 from the
flash on my board, which holds 128M flash and 64M RAM.

Now, I can use a serial blaster to boot into the redboot prompt. But I found
that the compiled redboot can not work with my flash. My flash is SAMSUNG
K9F1G08U0B, whose page size is 2K. Therefore, my redboot can not recognize
the flash. When I try to "fis write" the bootrom file into the flash, the
error information is as follows:

Invalid FLASH address 0x60000000: FLASH sub-system not initialized
     valid range is 0x00000000 - 0x00000000

When I typed in "version" under redboot prompt, the information is as
follows:

RAM: 0x00000000 - 0x02000000 [0x00053750 - 0x01ffd000] available
FLASH: 0x00000000 - 0x00000001, 0 blocks of 0x00000000 bytes each.

So, could anybody share your redboot with me to fix this problem about
enabling nand 2k flash? Thank you so much.

Best Regards,
Lux
