Re: [XenARM] INITRAMFS SOURCE Path

[See-Hwan Yoo <seehwan.yoo@xxxxxxxxx>]

Hello, comson
I think that the bootloader is not a big problem.
tftp simply transfers the file from the host system to the given memory area.
You can do it with the blob, also.
Locate xen-bin and vmlinux in proper memory region, and run the xen-arm.
Hope to be helpful!

ps. u-boot for iMX-21 can be found in the freescale's web site.
