Subject: [PATCH V2] Fix regression of commit 87b533bf
From: Kevin O'Connor <kevin@xxxxxxxxxxxx>
After adding more device entries in ACPI DSDT tables,
the filesize of bios.bin changed from 128K to 256K.
But bios could not initialize successfully.
This is a regression since seabios commit 87b533bf. Prior to
that commit, seabios did not mark the early 32bit initialization
code as init code. However, a side effect of marking that code
(handle_post) as init code is that it is more likely the linker
could place the code at an address less than 0xe0000.
The patch (just a hack) would cover up the issue.
