Kees Cook cb18ef0da2 x86/boot: Add missing file header comments
There were some files with missing header comments. Since they are
included from both compressed and regular kernels, make note of that.
Also corrects a typo in the mem_avoid comments.

There is no write to serial routine, no need for XMTRDY macro.

Yinghai Lu 74b3c444a9 x86, setup: Fix earlyprintk=serial,0x3f8,115200
earlyprintk can take and I/O port, so we need to handle this case in
the setup code too, otherwise 0x3f8 will be treated as a baud rate.

Yinghai Lu 83d9f65bda x86, setup: Fix earlyprintk=serial,ttyS0,115200
Torsten reported that there is garbage output,
after commit 8fee13a48e (x86,
setup: enable early console output from the decompressor)

It turns out we missed the offset for that case.

Yinghai Lu f4ed2877b1 x86, setup: reorganize the early console setup
Separate early_serial_console from tty.c

This allows for reuse of
early_serial_console.c/string.c/printf.c/cmdline.c in boot/compressed/.

-v2: according to hpa, don't include string.c etc
-v3: compressed/misc.c must have early_serial_base as static, so move it back to tty.c
     for setup code
