Subject: [PATCH v2 0/2] board: sifive: unmatched: use zero copy for initrd
Date: Tue,  9 Nov 2021 15:45:59 +0100	[thread overview]
Message-ID: <20211109144601.92326-1-heinrich.schuchardt@canonical.com> (raw)

Booting Ubuntu Impish showed the following output:

    relocaddr   = 0x00000000fff60000

    Loading Ramdisk to fa118000, end fffff19d ...

The initrd is overwriting the U-Boot binary. Booting fails.

There is no need to copy the initrd from $ramdisk_addr_r.
Set init_high = ~0UL to use zero copy. Do the same for the device tree.

Rearrange all load addresses:

* put the small files below $kernel_addr_r to not limit the kernel size.
* ramdisk_addr_r should be the highest of all loading addresses to
  avoid limiting the size of the initial RAM disk.

v2:
	rearrange all more addresses
