From: David Bauer Date: Sun, 2 Apr 2023 15:52:16 +0000 (+0200) Subject: mpc85xx: reserve upper 1MB of RAM for WS-AP3825i X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1d4d21481fcd75a07be081ddb4044ee5ae457b93;p=openwrt%2Fstaging%2Fblocktrron.git mpc85xx: reserve upper 1MB of RAM for WS-AP3825i The bootpage for the second core is placed by U-Boot in the upper 128k of syste-memory. This could either be a reserved-area or deducted from the total system-memory. As only the latter is parsed by the bootwrapper, reduce the available system memory for linux in order to preserve the bootpage from being overwritten.
