phyCORE-i.MX 91/93

U-Boot for the phyCORE-i.MX 91/93. Both SoC variants, that is i.MX 91 and i.MX 93, are supported by same board code, however each variant uses different defconfig and ATF/ELE firmware blobs. Please follow the correct steps for the populated SoC.

Quick Start

Note: srctree is U-Boot source directory Get ATF from: https://github.com/nxp-imx/imx-atf/ branch: lf_v2.12

For phyCORE-i.MX 91 variant:

$ unset LDFLAGS
$ make PLAT=imx91 bl31
$ cp build/imx91/release/bl31.bin $(srctree)

For phyCORE-i.MX 93 variant:

$ unset LDFLAGS
$ make PLAT=imx93 bl31
$ cp build/imx93/release/bl31.bin $(srctree)
