[PATCH 2/5] arm: mvebu: Add CRS326-24G-2S board
Luka Kovacic
luka.kovacic at sartura.hr
Thu Jul 23 10:56:37 CEST 2020
MikroTik CRS326-24G-2S board has a switch chip with an integrated
Marvell Prestera 98DX3236 CPU.
This commit includes two board variants, namely the factory
default one and a Bit variant. The Bit board variant has a
bigger Macronix flash.
Add basic U-Boot, UART and SPI flash support.
