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().
