is now fixed.

Berkus Decker d85d824bfd Switch on MMU immediately to avoid unaligned access 
Since enabling armv6 unaligned access bit U in CP15 C1
requires AArch32 assembly and I don't want to introduce
yet another boot stub, I'll just initialize MMU right away
- this causes CPU to treat SCTLR_EL1.A differently and not
cause any alignment faults.

In the future, a small AArch32 boot stub that uses
now commented out fn enable_armv6_unaligned_access()
should be used to set U=1 and A=0 for full unaligned
access even when MMU is off. See ARM documentation
linked from that fn.

Berkus Decker 91e8652abc Merge pull-request #31 from metta-systems:fix/code-cleanup to develop 
Fix/code cleanup
* Set stack pointer immediately upon entry
* Disable alignment checks before enabling MMU (rust core lib likes to do unaligned half-word accesses from its fmt_u64 routine, which we use a lot)
* Print more detailed reports in kernel exception handler
* Clean up makefiles
* Dry up boot code
* Move build-std flags to cargo config, as they apply to all of the cargo invocations
* Remove rlibc dependency, use compiler built-ins instead

Berkus Decker 373f4753dc Disable alignment checks right on boot 
Specifically, before we print any numbers - rust
core fmt_u64 uses a little optimisation that
ldrh/strh to unaligned addresses.
