[U-Boot-Users] [PATCH] cfi-flash: Add?CFG_FLASH_AUTOPROTECT_LIST

[Matthias Fuchs]

Hi,

I tried this in cfi_flash.c:

struct apl_s   {
	ulong start;
	ulong size;
}

struct apl_s apl[] __attribute__((weak)) = {};

I added a redeclaration of apl into my board code.

Now I ran into the problem that the ARRAY_SIZE macro
on apl in cfi_flash.c does not take care of the redeclation. So
it evaluated to 0 instead of the real size of the array
from my board code.

Now I could

a) add a delimiter to the apl array (e.g. size=0 for the last entry)
b) implement Stefan approach
c) ???

Any idea?

Matthias
