[PATCH 1/4] hw/loongarch/boot: Remove unnecessary cast to target_ulong

[Philippe Mathieu-Daudé]

Reduce initrd_size scope. It is already of signed type (ssize_t),
no need to cast to unsigned for the comparison.

[PATCH 3/4] target/loongarch: Remove target_ulong use in gdb_write_register handler

[Philippe Mathieu-Daudé]

ldq_le_p() returns a uint64_t type, big enough to also hold
ldl_le_p() return value. If we were building for a 32-bit
LoongArch target, ldq_le_p() would not fit in target_ulong.
Better stick to plain uint64_t.

[PATCH 4/4] target/loongarch: Do not use target_ulong type for LDDIR level

[Philippe Mathieu-Daudé]

The LDDIR level page table is a 5-bit immediate. Using the
uint32_t type for it is sufficient. Avoid the target_ulong type.
