I don't know if it's possible to implement a weak structure, but I
would prefer something like this instead of your original
implementation (no #ifdef's in the code):
struct apl_s {
u32 start;
u32 size;
};
#if !defined(CFG_FLASH_AUTOPROTECT_LIST)
struct apl_s apl[] = { };
#else
struct apl_s apl[] = CFG_FLASH_AUTOPROTECT_LIST;
#endif
And then later in the code:
+ for (i = 0; i < ARRAY_SIZE(apl); i++) {
+ debug("autoprotecting from %08x to %08x\n",
+ apl[i].start, apl[i].start + apl[i].size - 1);
+ flash_protect (FLAG_PROTECT_SET,
+ apl[i].start,
+ apl[i].start + apl[i].size - 1,
+ flash_get_info(apl[i].start));
+ }
What do you think?
