The above looks like a subset of what printenv returns in u-boot. To set 
it the equivalent incantation would be:

setenv media_addr_r '0x4001000000'
setenv media_img 'mp30ar0_tianocore_media.img'
setenb spi_load=tftp '${media_addr_r} ${user_dir}/${media_img}'
setenv spi_update=sf 'probe 0; sf erase 0x0 ${filesize}; sf write 
${media_addr_r} 0x0 ${filesize}'

Apologies for the extra linebreak on the last line due to MUA wrapping 
the lines.

Michael raised this issue earlier. Even though the MAC addresses are set 
correctly in u-boot, it looks like the kernel doesn't pick it up.
