Subject: [PATCH] kern: Add %X option to printf functions
The printf(3) function has support for the %X format specifier, to output
an unsigned hexadecimal integer in uppercase.
This can be achived in GRUB using the %x format specifier in grub_printf()
and calling grub_toupper(), but it is more convenient if there is support
for %X in grub_printf().
