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

[Cuong Dang Phu]

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.

There symbols are for PCMCIA controller .
SE7727 has Marubun PCMCIA controller(MR-SHPC-01).

SE7727 has Interrput controller on FPGA.
These symbols are written in the manual. 

I think that You may not worry about these, maybe.

Now, I had basic know basic knowledge about PCMCIA and FPGA

i have three documents: 
    SH7727 Group Hardware Manual.
    T-Kernel/SE Standard device driver for T-Engine/SH7727 Installation Manual.
    Hitachi SuperH™ RISC engine SH-3/SH-3E/SH3-DSP Programming Manual.
But i can't find those symbols. 

I’m a young man and i don’t know Japan Language, if I make mistake, please 
forgiving me and help me to understand it. Thank you very much.

The manual of T-Engine and the manual of Solution Engine are 
different. 
Moreover, it doesn't serve as a reference so much because the kind of 
the board is also different.

Sorry, Manual is SE7727's manual.
These are not written in the manual of CPU.

No Problem.

I found this document: SH7727　T-Engine Board 取扱説明書(MS7727CP02), and I 
think it is manual which you told me. But it is Japan version, do you have 
English version?

Thank for you help,

I miss-writed.

The macro that you mind is a thing of Solution Engine 7720.
And the board which you develop is SH7727 T-Engine Board.
These are totally different boards. I think that I do not serve as a
reference very much.

If you want to know the macrocontents which you point out by the first email ,
you need get a manual of *Solution Engine 7720*.

This point doesn't write in SH7727 T-Engine Board and SH7727 CPU of manual.

 Nobuhiro

You are right, the board which I develop is SH7727 T-Engine Board and we use 
Solution Engine 7720 as an example. I understood you idea, and now, I think I 
can understand things which I wrote in the first email. 

Thank you very much
