Subject: ACPI: tables: Print RINTC information when MADT is parsed
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4d02d88d2b922807307a3574a7b401dcccb870d1;p=linux.git

ACPI: tables: Print RINTC information when MADT is parsed

When MADT is parsed, print RINTC information as below:

ACPI: RISC-V INTC (acpi_uid[0x0000] hart_id[0x0] enabled)
ACPI: RISC-V INTC (acpi_uid[0x0001] hart_id[0x1] enabled)
...
ACPI: RISC-V INTC (acpi_uid[0x000f] hart_id[0xf] enabled)

This debug information will be very helpful during bring up.
