# The GICv3 & ITS drivers allocation needs are:

# - LPI pend table: for each redistributor/cpu 1x64K aligned on 64K

# - Interrupt Collections table: 1x4K aligned on 4K

# This makes 11x64K to permit all allocations to success.

# Note, will need 64K HEAP_MEM per CPUs added.

# With 11x64K HEAP, up to 116 ITT tables of 32 ITEs can be allocated.
