ppc/pnv: Set default RAM size to 1 GB
The memory layout of the PowerNV machine is defined as :
#define KERNEL_LOAD_BASE ((void *)0x20000000)
#define KERNEL_LOAD_SIZE 0x08000000
#define INITRAMFS_LOAD_BASE KERNEL_LOAD_BASE + KERNEL_LOAD_SIZE
#define INITRAMFS_LOAD_SIZE 0x08000000
#define SKIBOOT_BASE 0x30000000
#define SKIBOOT_SIZE 0x01c10000
#define CPU_STACKS_BASE (SKIBOOT_BASE + SKIBOOT_SIZE)
#define STACK_SHIFT 15
#define STACK_SIZE (1 << STACK_SHIFT)
The overall size of the CPU stacks is (max PIR + 1) * 32K and the
machine easily reaches 800MB of minimum required RAM.
Any value below will result in a skiboot crash :
[ 0.034949905,3] MEM: Partial overlap detected between regions:
