Base 16 number printing used digits[33] instead of the more readable 'x'
for the "0x" prefix. That means you have to look up an array just to
find out what the code does. Change it.
We already write "<NULL>" if printk gets a NULL pointer as string
argument. Introduce "<near NULL>" for string arguments with addresses
below 0x400. This error happened in the past when dereferencing a struct
member with a string and the struct had the address NULL.
Check if all to-be-printed characters in the string are indeed
printable. The idea is to catch garbage strings from stray pointers and
print "<non-ASCII characters>" instead.
If a string contains characters outside classic ASCII printable stuff,
this will trigger. An example would be characters with diacritic marks
like äöüéăçőč.
Then again, I don't see localized versions of coreboot on the horizon.
Maybe for payloads, but not for coreboot itself.
