[Qemu-arm] [PATCH 05/14] hw/arm/bcm2835_peripherals: Name various address spaces

[Philippe Mathieu-Daudé]

Various address spaces from the BCM2835 are reported as
'anonymous' in memory tree:

  (qemu) info mtree

  address-space: anonymous
    0000000000000000-000000000000008f (prio 0, i/o): bcm2835-mbox
      0000000000000010-000000000000001f (prio 0, i/o): bcm2835-fb
      0000000000000080-000000000000008f (prio 0, i/o): bcm2835-property

  address-space: anonymous

bcm2835-gpu-ram-alias[*] @ram 0000000000000000-000000003fffffff

  [...]

Since the address_space_init() function takes a 'name' argument,
set it to correctly describe each address space:

  (qemu) info mtree

  address-space: bcm2835-mbox-memory
    0000000000000000-000000000000008f (prio 0, i/o): bcm2835-mbox
