Warner Losh dea3eef94c uart: Ingore pl011 historic mistakes
Some veresions of EDK-II and QEMU reported the wrong values for the
register shift and the region I/O size. Detect those and set it to the
correct values. In general, anything other than a shift of 2 and a
regio width of 4 (bytes, or 32 bits) is a mistake. However, allow
for overrides in the future by only overriding the buggy values.
Otherwise, we will fail to boot.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
