Hi all, this is v7 of [1][2][3][4][5][6]!
There was a discussion recently on the mailing lists regarding our
management of memory above ram_top [0]. The tl;dr is that we have two
problems.
The first one is that U-Boot always relocates to the top of the first
available
bank unless there's special board code to sidestep that. The second is
we don't
successfully deal with devices that can only do 32-bit DMA.
This patch series deals with the first problem by adding a Kconfig
option
allowing platforms to relocate to the top of the last discovered bank.
It's worth noting that this is easily testable with QEMU
Following discussion on patch 1/7 in v5, I boot tested this v7 series on
one of my powerpc boards. It could start Linux kernel v7.0 without any
problem.
FWIW,

That is really nice, thank you.
Which PPC board did you use ?
