x86 CPUs start up in 16-bit mode, even if they are 64-bit CPUs. This code
|
|
must be placed at a particular address. This entry holds that code. It is
|
|
typically placed at offset CONFIG_SYS_X86_START16. The code is responsible
|
|
for changing to 32-bit mode and starting TPL, which in turn jumps to SPL.
|
|
|
|
If TPL is not being used, the 'x86_start16_spl or 'x86_start16' entry types
|
|
may be used instead.
