Update README.md to recommend passing CROSS_COMPILE via env

Building u-boot should pass CROSS_COMPILE via the environment
rather than a make variable; some ARM64 boards require parts of
the bootloader to be built w/ 32-bit toolchains, setting
CROSS_COMPILE via a make variable prevents that override from
working.

u-boot

This is a version of u-boot, modified to support Fuchsia on the Khadas vim2, vim3, and NXP imx8mevk boards.

The master branch in this repository is empty.

Please check out one of the platform specific branches, like vim2 or imx8mevk for access to the source.

u-boot uses the Gerrit code review system to review and accept patches. Our instance is located at [https://third-party-mirror-review.googlesource.com/]. Please take a look at the CONTRIBUTING file and at that link if you're interested.

Building vim2 Bootloader

To build the vim2 bootloader for Fuchsia:

Prerequisites - arm and aarch64 toolchains. On Debian/Ubuntu systems, for example:

apt-get install gcc-arm-none-eabi gcc-aarch64-linux-gnu
  1. Check out the vim2 branch
git checkout -b vim2 origin/vim2
  1. Configure the target
make kvim2_defconfig
  1. Build u-boot.bin
CROSS_COMPILE=aarch64-linux-gnu- make

You now have a u-boot.bin that you can flash to a target with using fastboot.
