It looks like that discussion was about a 'missing' dtb file, device
tree therefor no terminal to display kernel bootup info.
I use the command in u-boot to pass the blob location in sdram.
bootz 0x40400000 - 0x40700000
my boot arguments are
bootargs=earlyprintk console=ttyAMA0,115200n8 mem=nopentium
I dont think that the kernel ever gets to that point because it seem
to lockup when the mmu is enabled.
head.S - command
mcr p15, 0, r0, c1, c0, 0 @ write control reg
To see what would happen I did comment out that line and the kernel
continued on for a little while, finding the device tree blob.
All of my debugging says that this line locks up the cpu.
I don't believe that the kernel ever gets to the point of using the blob.
Am I completely wrong here?
I have not updated my code from linux-fslc since June (30 days old
code) this year because it looks like a lot of changes are going on to
up to linux 4.x.
