[U-Boot] [U-boot] [Patch v2 0/6] keystone2: add k2l SoC and k2l_evm board support
This patch series adds Keystone II Lamar (K2L) SoC and k2l_evm board support.
Based on "[U-boot] [Patch v2] keystone: usb: add support of usb xhci" https://patchwork.ozlabs.org/patch/386506/
v2..v1 Rebased according to changes of c338f09e965a300ddd78af73e86c4af4c9464ce4 "keystone: kconfig: move board select menu and common settings"
Hao Zhang (6): ARM: keystone2: add K2L device hardware definitions keystone2: clock: add K2L clock definitions and commands keystone2: msmc: add MSMC cache coherency support for K2L SOC ARM: keystone2: spl: add K2L SoC support keystone2: enable OSR clock domain for K2L SoC keystone2: k2l-evm: add board support
