e3ffad684f [scripts] make sure all the do-qemu* scripts exec qemu as the last line 
This helps a wrapper script test for proper exit.

64b462cb37 [arm][v9p] Add v9p host dir sharing support for arm platform 
- Add the v9p support for arm platform.
 - Add an option `-f` to set the shared directory on the host machine to
   `do-qemuarm`.
 - For example, to use the v9p dir sharing, run the script as:
    ```
    # under `lk/` run the follow command will share the current
    # directory `lk/` within LK vm as VirtIO 9p device
    scripts/do-qemuarm -f .
    ```

4a15661ee0 [arch][arm64] use SMC when booted at EL2 in QEMU 
If we were booted at EL2 (e.g. when passing -machine
virt,virtualization=on), we need to use SMC instead of HVC for PSCI
calls. Change psci_call() to do this and add a flag to do-qemuarm to
allow testing this scenario.

36e73e0fac [bus][pci] add routines to pass in PCI bus resources prior to starting the pci bus manager 
Wire them up on arm and riscv which need them. x86-pc does not, so dont
call it.

Also fix a few miscellaneous bugs, notably PCI not detecting 64bit bars
properly due to an off by one bit error.

a47cf76f14 [scripts][do-qemuarm] hard disable network if not selected 
Turns out qemu was putting a e1000 nic on the PCI bus if no options were
selected. No reason to do so if the network is explicitly not called
for.

ae5200595c [platform][riscv-virt] added support for QEMU's riscv 'virt' machine 
The virt machine is a generic target, much like the arm virt machine.
Intended to be simple to use and a good target to run large systems like
linux on. At the moment simply support booting and simple uart and timer
support.

12868bf6c0 [lib][heap] Add Cmpctmalloc as an alternative malloc implementation 
From scratch simple binning heap. Complexity wise in the middle
between miniheap and dlmalloc. Generally much faster than miniheap
with a small amount of memory overhead. Performs similarly to
dlmalloc.

31de0ff388 [platform][qemu-virt] read the memory size out of the FDT using libfdt 
-Bump the kernel forward by 64K
-Look for the FDT that qemu leaves around in the space just before the kernel
-Pick out the 'memory' node, parse the base/length values and patch the main
    pmm arena before adding it
