The driver used to use the serial port configuration as left by the
boot rom until very late into the initialization. As I have said many
times in the past, the serial driver went through three different
levels of configuration. There was an early configuration that was
used for kgdb, a later one used by the serial kernel printk, and
finally a full configuration by the serial driver.
It's sad that "moving forward" is done at a cost of throwing away
features that were important. The hack to allocate from boot memory
is a quick fix, but this further ensures features like pinned TLB
entries won't work.
Thanks.
