[PATCH] hw/arm/nseries: Fix loading kernel image on n8x0 machines

[Philippe Mathieu-Daudé]

Commit 7998beb9c2e removed the ram_size initialization in the
arm_boot_info structure, however it is used by arm_load_kernel().

Initialize the field to fix:

  $ qemu-system-arm -M n800 -append 'console=ttyS1' \
    -kernel meego-arm-n8x0-1.0.80.20100712.1431-vmlinuz-2.6.35~rc4-129.1-n8x0
  qemu-system-arm: kernel 'meego-arm-n8x0-1.0.80.20100712.1431-vmlinuz-2.6.35~rc4-129.1-n8x0' is too large to fit in RAM (kernel size 1964608, RAM size 0)

Noticed while running the test introduced in commit 050a82f0c5b
("tests/acceptance: Add a test for the N800 and N810 arm machines").

Fixes: 7998beb9c2e ("arm/nseries: use memdev for RAM")

Fixes the test in "make check-acceptance" for me:

Applied to target-arm.next, thanks.
