Subject: [U-Boot] [PATCH 01/14] x86: minnowmax: Adjust U-Boot environment address in SPI flash
Date: Mon, 9 May 2016 02:34:24 -0700 [thread overview]
Message-ID: <1462786477-14036-2-git-send-email-bmeng.cn@gmail.com> (raw)
In-Reply-To: <1462786477-14036-1-git-send-email-bmeng.cn@gmail.com>
Currently U-Boot environment address is at offset 0x7fe00 of a 8MB
SPI flash. When creating a partial u-boot.rom image without flash
descriptor and ME firmware, U-Boot actually occupies the last 1MB
of the flash, and reprograming U-Boot causes previous environment
settings get lost which is not convenient during testing.
Adjust the environment address to 0x6ef000 instead (before the MRC
cache data region in the flash).
