Subject: arm: apple: Switch to board based text env
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0f0ff73bac5dc43f8fe336f2828900035e260f1a;p=thirdparty%2Fu-boot.git

arm: apple: Switch to board based text env

The main use case for u-boot on Apple silicon based devices is to
provide an EFI based bootloader for operating systems. This uses a
generic u-boot image with DTBs passed from an earlier boot loader
(m1n1). Use the generic board name "mac" for this purpose.
