Subject: arm: mvebu: turris_omnia: Define only one serdes map variable
X-Git-Tag: v2025.01-rc5-pxa1908~1425^2~14
X-Git-Url: http://git.dujemihanovic.xyz/img/html/index.html?a=commitdiff_plain;h=8ead243ecc2c5073cff3bd9dfb4c4fcab8c2a94a;p=u-boot.git

arm: mvebu: turris_omnia: Define only one serdes map variable

By default use primary serdes map with PCIe function in combined
miniPCIe/mSATA slot. When SATA is detected change serdes map variable at
runtime.
