Subject: [PATCH v8 01/14] MIPS: spaces: Define a couple of handy macros
Date: Fri, 16 Feb 2024 18:42:10 +0100 [thread overview]
Message-ID: <20240216174227.409400-2-gregory.clement@bootlin.com> (raw)
In-Reply-To: <20240216174227.409400-1-gregory.clement@bootlin.com>
Define KSEGX_SIZE to represent the size of each KSEG segment.
Introduce CKSEG0ADDR_OR_64BIT and CKSEG1ADDR_OR_64BIT to get an XPHYS
address in 64bits and CKSEG[01]ADDR() in 32 bits mode.
Co-developed-by: Jiaxun Yang <jiaxun.yang@flygoat.com>
