35fddd5117 proxy: linux.py: allow to load u-boot before Linux
right now u-boot can bring up the PCIe bus such that Linux only requires
a very minimal driver. this new --u-boot flag for linux.py allows to
load u-boot before the Linux kernel to make use of this.
This requires a small hack to inject the booti command into the default
u-boot boot environment.

8af8dadee1 memory: Support L3 mappings, map m1n1 code as RX.
This replaces the old pagetable code with an adapted version of what
hv_vm.c does, which can handle block and page mappings more
intelligently.

Then, map the m1n1 code section as RX. This allows us to work in modes
where W^X is enforced.
