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 SPL, which in turn changes to
|
|
64-bit mode and jumps to U-Boot (for 64-bit U-Boot).
|
|
|
|
For 32-bit U-Boot, the 'x86_start16' entry type is used instead.
