Hi all,
We are working on customized board with amcc 440SPe
processor & xilinx System Ace controller. The System
Ace controller is connected to compact flash driver.
We use u-boot 1.2 as bootloader & linux kernel
2.6.16-2.
On the process the u-boot is able to detect compact
flash through Xilinx SystemAce controller & able to
load the kernel image into compact flash.But when the
linux boot's up it not able to detect the System Ace
controller or compact flash.
Note:we need to have the root file system in compact
flash.
Is their any drivers available for SystemAce
controller on linux 2.6,if their how to get it.please
help me in this
with regards
raja

The System Ace controller is connected to compact flash driver. We use u-boot 1.1.2 as bootloader & linux kernel - 2.6.16-2. System ace is connected to amcc440SPE processor via GPIO and External Peripheral Bus Controller(EBC). While booting the linux, it crashes when i am trying to access(read/write) a system ace register. In the u-boot though i have support, as of now i am not doing anything with system ace as it not required now. In u-boot/include/configs/custom_board.h, i could see #define CFG_ACE_BASE 0xe0000000 /* Xilinx ACE controller - Compact Flash */ So i have used this address in Linux driver to to ioremap to access the ace registers. Though i could do ioremap, it crashes while booting exactly when it is trying the access any ace register. I doubt with the address i have used . But could not get any clue from the docs given. I want to know how to access the system ace registers and how to get the address to ioremap. Please let me know if any details required and also if i am missing any fundamentals.

The driver is connected to the processor through IRQ4 . So, in xparameter_ml300.h , I have changed the #define XPAR_OPB_INTC_0_SYSACE_COMPACTFLASH_SYSACE_IRQ_INTR 4 Also, in "xsysace_init", if I have xsa_device.gd = alloc_disk(16); , then the kernel hangs. So I have assigned alloc_disk(1), in which case the kernel boots-up fine. But when I issue 'fdisk / mount ', it goes through - ' XSysAce_SectorRead' which is being called from "xsysace_do_request". And at the nd of the function it hangs. I couldn't trace exactly where it hangs. Could you please suggest some pointers to debug on this issue? This is very critical for us and I am held up with this issue for the last 1 week. Thanks so much for all your help.

The PPC440 implements a 36 bit memory map. So i changed my ioremap to ioremap64 and gave the 36-bit physical address which includes EPN and is 0x5d0000000ULL and it returns a 32-bit virtual pointer with which am able to access the device registers.
