[ECOS] Re: Redboot v2.04, IXP4XX and Flash v2

[Antonello Lombardinilo]

Hi Tom, 

i replace io/flash, dev/flash and redboot directories
with latest flash v2 snapshot from ecoscentric ftp server.
I made some change to compile:
 - add devs/flash/arm/kixrp435 directory;
 - replace redboot/current/include/redboot.h with original file 

The compilation seems to work fine.
I try to enable FLASH_V2 support. I replace CYGPKG_DEVS_FLASH_STRATA
with CYGPKG_DEVS_FLASH_STRATA_V2 in ecos.db and
hal/arm/xscale/kixrp435/current/misc/redboot_RAM.ecm 

When I try to import configuration I get a following error:
[root@AntoPC001 kixrp435_npe_RAM]# ecosconfig new kixrp435_npe redboot
U CYGHWR_HAL_ARM_XSCALE_CPU, new inferred value IXP43x
U CYGSEM_HAL_USE_ROM_MONITOR, new inferred value 0
U CYGIMP_HAL_COMMON_INTERRUPTS_USE_INTERRUPT_STACK, new inferred value 0
[root@AntoPC001 kixrp435_npe_RAM]# ecosconfig import 
/home/antonello/projects/eCos/redboot-intel-ixp4xx-070320/packages/hal/arm/x

[root@AntoPC001 kixrp435_npe_RAM]# 

I want test flash v2 on kixrp435 board to make sure that the hardware works.
The kixrp435 board have 2 flash chips: strata flash and nand flash.
