I pull the lastest ng code from svn and did cross-compile:

make[3]: *** [ah_osdep.o] Error 1
make[3]: Leaving directory `/home/bcheng/snapgear/madwifi-ng/ath_hal'
The errors are from ../hal/linux/ah_osdep.h
#define _OS_REG_WRITE(_ah, _reg, _val) do { \
if ( (_reg) >= 0x4000 && (_reg) < 0x5000) \
writel((_val), (volatile u_int32_t *)((_ah)->ah_sh + (_reg)));\
else \
writel(__bswap32(_val), (volatile u_int32_t *)((_ah)->ah_sh + (_reg))); \
} while (0)
I fixed Error by adding a typecast (u32) to
writel((_val), (volatile u_int32_t *)((_ah)->ah_sh + (_reg)));\
But later I received "unable to attach hardware - HAL status 13" error

Then I looked at the ../hal/linux/ah_osdep.h from /!svn/ver/1394/trunk
It has a different definition. there is no ( *) pointer typecast
in writel() and readl()
#define _OS_REG_WRITE(_ah, _reg, _val) do { \
if ( (_reg) >= 0x4000 && (_reg) < 0x5000) \
writel((_val), (volatile unsigned long)((_ah)->ah_sh + (_reg)));\
else \
writel(__bswap32(_val), (volatile unsigned long)((_ah)->ah_sh + (_reg))); \
} while (0)
I used this definition and didn't see any compilation error
but I received the same error from insmod ath_pci.o
# insmod ath_pci.o
Using ath_pci.o

However, the madwifi-ng from /!svn/ver/1349/trunk works fine
on my ixp425-based board. No compilation error, no (HAL status 13) error
I'm running linux 2.4.24, using XSCALE processor with big-endian configuration.
I looked at the ../hal/linux/ah_osdep.h file, there is no
writel() in _OS_REG_WRITE()
I'm confused, ah_osdep.h constantly been changing.
