At present binman has a single entry type for the 16-bit code code needed to start up an x86 processor. This entry is intended to include both the reset vector itself as well as the code to move to 32-bit mode.
However this is not very flexible since in some cases other data needs to be included at the top of the SPI flash, in between these two pieces. For example Intel requires that a FIT (Firmware Image Table) pointer be placed 0x40 bytes before the end of the ROM.
To deal with this, add a new reset entry for just the reset vector. A subsequent change will adjust the existing 'start16' entry.

Applied to u-boot-dm, thanks!
