[U-Boot] [PATCH 00/23] MIPS Boston fixes, ethernet support & cleanup

[Paul Burton]

This series fixes a few things with the primary aim of enabling use of
the ethernet controller found in the Intel EG20T Platform Controller Hub
that is connected to one of the Xilinx AXI to PCIe controllers in the
system. Thus the series makes fixes across the PCIe driver & PCI
subsystem, the ethernet driver & the board code.

With this series applied it is possible to load a Linux kernel image
over ethernet on a MIPS Boston board & successfully boot it to a state
where it can access the PCI devices in the system for itself.


Paul Burton (23):
  image: Use ram_top, not bi_memsize, in getenv_bootm_size
  MIPS: Use ram_top, not bi_memsize, in arch_lmb_reserve
