6726 spimaster bootloader支持flash的型号有哪些
本来只要是符合Motorola的SPI EEPROM协议的就行。
The bootloader supports devices obeying the standard SPI serial EEPROM protocol established by
Motorola.
但是呢,勘误表13页说明C6727B即silicon revision 1.2最好不要用SPI master bootmode。

Advisory 1.2.2 Do Not Use SPI Master Boot Mode for Silicon Revision 1.2/C9230C100 ROM
Revision(s) Affected: 1.2
Details: The C9230C100 ROM bootloader does not handle the change described in Usage Note 1.2.8:
Clearing of SPI Interrupt Flags may be Blocked by Simultaneous Set Condition correctly when
it polls the SPI in the SPI Master boot mode. This can result in a failure to boot. The problem
can be affected by timing variations on silicon and therefore may not appear on all devices.
Workaround: None
