* Move the spi vendor list from Esp.h to its own header in eboot. * Fix ifdef issue with spi_vendors.h * Add initFlashQuirks() for any chip specific flash initialization. Called from user_init(). * namespace experimental for initFlashQuirks() * Slow down flash access during eboot firmware copy Part 1 - still some work to do * Slow down flash access during eboot firmware copy on XMC chips Part 2 - Identify the chip type. Note: there may still be issues with the access speed change. This is very much experimental. * Commit eboot.elf Co-authored-by: Develo <deveyes@gmail.com> Co-authored-by: Earle F. Philhower, III <earlephilhower@yahoo.com>
