From: Simon Glass Date: Thu, 21 Jan 2021 20:57:06 +0000 (-0700) Subject: spl: Tidy up SPL/TPL malloc sizes X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1426174f3fb0727321531504afbde110ef716573;p=u-boot.git spl: Tidy up SPL/TPL malloc sizes The current help talks about relocation which doesn't apply to SPL and TPL. Update it to avoid confusion. Also make the TPL size default to the same as the SPL size, since this is more likely to be a useful value than the one used by U-Boot proper, which may be quite a bit larger.
