From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Thu, 21 Jan 2021 13:57:06 -0700 Subject: [PATCH 01/11] spl: Tidy up SPL/TPL malloc sizes In-Reply-To: <20210121205716.964652-1-sjg@chromium.org> References: <20210121205716.964652-1-sjg@chromium.org> Message-ID: <20210121205716.964652-2-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de 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.
