Hi,
I am trying to compile uboot 1.3.1 for arm926ejs processor. i am using CodeSourcery arm-none-linux-gnueabi toolchain (gcc version 4.2.1 (CodeSourcery Sourcery G++ Lite 2007q3-51)) .
i am trying to write a driver for our on board mmc controller. i need to do multiply and divide operation as below.
unsigned long long c; static int lc69_mmci_clk = 0; unsigned int timeout_ns;
<snip> <snip> <snip>
c = (unsigned long long)timeout_ns * lc69_mmci_clk; c = c / 1000000000UL;
<snip> <snip>
while compilling i am getting an error as below.

when i checked on the internet for this error few (http://bugzilla.openmoko.org/cgi-bin/bugzilla/attachment.cgi?id=7&actio n=view) recommended about removing -mabi from config script.
-PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) +PLATFORM_CPPFLAGS +=$(call cc-option) PLATFORM_RELFLAGS +=$(call cc-option,-mshort-load-bytes,$(call cc-option,-malignment-traps,))
when i try this, i get a different error.

Does anyone has a better solution for this.
Thanks in advance
