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, Cuong Dang Phu
