Here is the changelog again in case everyone's mailer mangled it as
badly as mine did.

> I think this is very close.  There are a few things to work out that
> I'd like help with.
> 1. If I set a variable like UCLIBC_VER in the
> config/platforms/serengeti_cheetah-x86_64.conf file, it doesn't make
> it to uclibc.mk

> 2. Could someone that has the actual hardware see if you need to
> comment out soft_resest_x in cache_as_ram_auto.c, or if that's a
> SimNow issue? (LinuxBIOS enters an infinite loop resetting itself if
> the reset is not commented out)

> Thanks,

> Here's the change log for the patch

> added config/platforms/serengeti_cheetah-x86_64.conf

> added PLATFORM_SERENGETI_CHEETAH_64 to config/platforms/Config.in

> changed config/platforms/serengeti_cheetah.conf to point to its own linuxbios make file instead of generic-linuxbios.mk

> changed scripts/Makefile.lab to use bzImage instead of vmlinux for

> mkelfimage so that it works on x86_64

> updated Build.settings to include a UCLIBC_LOADER variable for 64-bit

> removed the magic number from bin/checkrom.sh (Was LinuxBIOS version and platform dependent) and changed it to an informational message

> added a kernel config file and .mk file

> changed packages/kernel/kernel.inc to be platform aware

> changed packages/busybox/busybox.mk to be platform aware

> added a defconfig for busybox with 64-bit uClibc

> added a defconfig for uClibc 64-bit

> added a uClibc version variable UCLIBC_VER to uclibc.mk (0.9.28 doesn't have resolve.S for x86_64)

> changed "Building target config file" to "Building target" because it is executing ./buildtarget

> added patches for Config.lb for serengeti_cheetah-payload and serengeti_cheetah-lab

> added serengeti_cheetah.mk

Sorry about the need to repost.
