[PATCH 1/5] configs: restrict am62ax wakup SPL size

2022-12-24T01:15:46Z

In its current form, the am62a's wakeup SPL is fairly small, however
this will not remain as more boot modes are eventually added. To protect
us from overflowing our ~256k of HSM SRAM, add limits and check during
the wakeup SPL build.
