[Gnuk-users] [PATCH] linker script: fix keystore_pool size

[Aurelien Jarno]

Gnuk supports RSA keys up to 4096 bits. This require 1024 bytes of
storage (p and q are 256 bytes, n is 512 bytes). The linker script
should therefore reserve 1024 bytes per key instead of 512.

In practice it's not an issue at all as all supported MCU have a page
size bigger than 1024 bytes and Gnuk use one page per key.
