Subject: [PATCH v2 2/6] arch: dts: am642-sk-u-boot: Disable main_sdhci0 DT node and define alias index 1 for main_sdhci1 node
Date: Mon, 26 Jul 2021 20:58:03 +0530	[thread overview]
Message-ID: <20210726152807.22991-3-a-govindraju@ti.com> (raw)
In-Reply-To: <20210726152807.22991-1-a-govindraju@ti.com>

A Wilink wireless device is connected to MMCSD0 subsystem and is not
supported in U-Boot. Therefore, disable main_sdhci0 device tree node in
U-Boot.

If main_sdhci0 device tree node is disabled then the the index of
main_sdhci1 node becomes 0 which leads to break in boot flow. Therefore,
add an alias to fix the index to 1.
