Subject: [PATCH edk2-platforms v3 12/24] Silicon/NXP: Move RAM retrieval from SocLib
Date: Wed, 15 Apr 2020 17:43:30 +0530 [thread overview]
Message-ID: <20200415121342.9246-13-pankaj.bansal@oss.nxp.com> (raw)
In-Reply-To: <20200415121342.9246-1-pankaj.bansal@oss.nxp.com>
From: Pankaj Bansal <pankaj.bansal@nxp.com>
RAM retrieval using SMC commands is common to all Layerscape SOCs.
Therefore, move it to commom MemoryInit Pei Lib.
Signed-off-by: Pankaj Bansal <pankaj.bansal@nxp.com>
---
Notes:
- sort headers alphabetically
- Moved DRAM region retrieval and Total DRAM size retrieval to separate
functions
- Fixed MemoryPeim function description
- Modified check on FoundSystemMem = TRUE to check the RAM region against
MemoryPeim function input arguments UefiMemoryBase and UefiMemorySize
- (!DramRegions[Index].Size) => (DramRegions[Index].Size == 0)
- (FoundSystemMem) => (FoundSystemMem == TRUE)
- Added explaination for starting for loop from the last DRAM region
