Subject: [PATCH v2 6/9] env: Enable SPI flash env for SiFive FU540
Date: Wed, 20 May 2020 00:53:37 +0530 [thread overview]
Message-ID: <20200519192340.16624-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20200519192340.16624-1-jagan@amarulasolutions.com>
SPI flash device on HiFive Unleashed has 32MiB Size.
This patch add SPI flash environment after U-Boot proper
partition with a size of 128KiB.
SPI flash partition layout(32MiB):
0 - 34 : reserved for GPT header
35 - 39 : unused
40 - 2087 : loader1 (SPL, FSBL)
2088 - 10279 : loader2 (U-Boot proper, U-Boot)
10280 - 10535 : environment
10536 - 65494 : rootfs
65528 - 65536 : distro script
Note: the loader1 must start from 40th sector even though
there are 6 free sectors prior since 40th sector is nearest
flash sector boundary.?
