X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=2d58dddf7a37ea548bb940de2db050f5fe1a582d;p=u-boot.git

ARM: dts: stm32: add stm32429-eval-u-boot dts file

   _ Add gpio compatible and aliases for stm32f469
   _ Add FMC sdram node
   _ Add "u-boot,dm-pre-reloc" for rcc, fmc, fixed-clock, pinctrl,
     pwrcfg and gpio nodes.
