RedBoot and Cirrus EP9315


Hallo,
There is many days I'm searching for a solution without result :-(
I have Cirrus Videon EP9315 motherboard.
My problem is I have 128 MB of RAM in two chip select lines (nSDCE0,
nSDCE3).
Every memory bank has 2x32MB of ram.
RedBoot can see only 64 MB, so I need somehow enable the nSDCE0 memory bank.
On the 503 page of EP9315 User Guide is a table where is written how to
enable the chip select line.
I tried to modify the ep93xx_misc.c file to:
#ifdef
CYGHWR_HAL_ARM_EDB93XX_DRAM_SIZE_64


X_ARM_MMU_SECTION(0x000, 0x000, 32, ARM_CACHEABLE, ARM_BUFFERABLE, ARM_ACCESS_PERM_RW_RW); X_ARM_MMU_SECTION(0x040, 0x020, 32, ARM_CACHEABLE, ARM_BUFFERABLE, ARM_ACCESS_PERM_RW_RW); X_ARM_MMU_SECTION(0xC00, 0x040, 32, ARM_CACHEABLE, ARM_BUFFERABLE, ARM_ACCESS_PERM_RW_RW); X_ARM_MMU_SECTION(0xC40, 0x060, 32, ARM_CACHEABLE, ARM_BUFFERABLE, ARM_ACCESS_PERM_RW_RW); #endif //CYGHWR_HAL_ARM_EDB93XX_DRAM_SIZE_64 without result :-( If there is anybody that know how to modify the RedBoot software to I would be very grateful. Bye.
