stuck on boot, no SSH available

[mk01]

the cursor thing is 99% lockup on loader overwriting memory already used by for instance kernel with initramfs -> so bad thing.

for years 0x0a0000 as memory address was working. then condition changed and 0x0a00000 was working. last update is changing to 0x1000000 .

removing initramfs to test should confirm or not. just keep in mind that initramfs might be needed to BOOT from USB media (might / might not). that means remove "initramfs" line only in case you boot from SD - so we are sure kernel MUST be able to boot without it (so we are really checking the initramfs loading memory address issue).
