/* SDK/bootrom uses this structure internally to account for flash size.
|
|
|
|
chip_size field is initialised during startup from the flash size
|
|
saved in the image header (on the first 8 bytes of SPI flash).
|
|
|
|
Other field are initialised to hardcoded values by the SDK.
|
|
|
|
** NOTE: This structure is passed to some bootrom routines and is therefore
|
|
fixed. Be very careful if you want to change it that you do not break
|
|
things. **
