Linux 2.6.22.11 on T-Engine/SH7727 (MS7727CP02) Development Kit - Mapping physical memory address

[Cuong Dang Phu <cuongdp@Cybersoft-VN.com>]

Hi,

We are working for an embedded software company, for R&D purpose, we are 
porting Linux on T-Engine/SH7727 (MS7727CP02) Development Kit. The first step 
we do is: define physical memory and peripherals (in this file: \include\asm-
sh\se7727.h), but we have some difficult:
	a. We can’t understand many symbols: I show you a list I get form Linux 
kernel 2.6.22.11 for se7720:
 
#define PA_PCIC         PA_PERIPHERAL   		/* MR-SHPC-01 PCMCIA */
#define PA_MRSHPC       (PA_PERIPHERAL + 0x003fffe0)    /* MR-SHPC-01 PCMCIA 
controller */
#define PA_MRSHPC_MW1   (PA_PERIPHERAL + 0x00400000)    /* MR-SHPC-01 memory 
window base */
#define PA_MRSHPC_MW2   (PA_PERIPHERAL + 0x00500000)    /* MR-SHPC-01 attribute 
window base */
#define PA_MRSHPC_IO    (PA_PERIPHERAL + 0x00600000)    /* MR-SHPC-01 I/O 
window base */
#define MRSHPC_OPTION   (PA_MRSHPC + 6)
#define MRSHPC_CSR      (PA_MRSHPC + 8)
#define MRSHPC_ISR      (PA_MRSHPC + 10)
#define MRSHPC_ICR      (PA_MRSHPC + 12)
#define MRSHPC_CPWCR    (PA_MRSHPC + 14)
#define MRSHPC_MW0CR1   (PA_MRSHPC + 16)
#define MRSHPC_MW1CR1   (PA_MRSHPC + 18)
#define MRSHPC_IOWCR1   (PA_MRSHPC + 20)
#define MRSHPC_MW0CR2   (PA_MRSHPC + 22)
#define MRSHPC_MW1CR2   (PA_MRSHPC + 24)
#define MRSHPC_IOWCR2   (PA_MRSHPC + 26)
#define MRSHPC_CDCR     (PA_MRSHPC + 28)
#define MRSHPC_PCIC_INFO (PA_MRSHPC + 30)

#define PA_FPGA		0xB7000000 	/* FPGA base address */

#define MRSHPC_IRQ0    	14

#define FPGA_ILSR1	(PA_FPGA + 0x02)
#define FPGA_ILSR2	(PA_FPGA + 0x03)
#define FPGA_ILSR3	(PA_FPGA + 0x04)
#define FPGA_ILSR4	(PA_FPGA + 0x05)
#define FPGA_ILSR5	(PA_FPGA + 0x06)
#define FPGA_ILSR6	(PA_FPGA + 0x07)
#define FPGA_ILSR7	(PA_FPGA + 0x08)
#define FPGA_ILSR8	(PA_FPGA + 0x09)
 
	b. We don’t know how to define these sysbols.

Best regards,
