---help---
at25_main is a tiny program that runs in ISRAM. at25_main will
enable SDRAM and configure the AT25 Serial FLASH. It will prompt
and then load an Intel HEX program into SDRAM over the serial
console. If the program is successfully loaded in SDRAM, at25_main
will copy the program at the beginning of the AT26 Serial FLASH.
If the jumpering is set correctly, the SAMA5D4 RomBOOT loader will
then boot the program from the serial FLASH the next time that it
reset.

This is the size of the partition at the beginning to the AT25
serial FLASH that will be used to hold the boot program. Since
this program must run from SRAM, there would be no purpose int
making this size any larger than the size of the internal SRAM.

/* Both the Ronetix and Embest versions of the SAMAD3x CPU modules include an
* Atmel AT25DF321A, 32-megabit, 2.7-volt SPI serial flash. The SPI
* connection is as follows:
/* The SAMA5D4-EK includes an Atmel AT25DF321A, 32-megabit, 2.7-volt SPI serial
* FLASH on board. The connection is as follows:
*
* AT25DF321A SAMA5
* --------------- -----------------------------------------------
* SI PD11 SPI0_MOSI
* SO PD10 SPI0_MIS0
* SCK PD12 SPI0_SPCK
* /CS PD13 via NL17SZ126 if JP1 is closed (See below)
* AT25DF321A SAMA5D4-EK SAMA5
* ---------- --------------- --------------------------------
* SI AT25_SPI0_SI PC1 PC1/SPI0_MOSI/PWML2/ISI_D9
* SO AT25_SPI0_SO PC0 PC0/SPI0_MISO/PWMH2/ISI_D8
* SCK AT25_SPI0_SPCK PC2 PC2/SPI0_SPCK/PWMH3/ISI_D10
* /CS AT25_SPI0_NCPS0 PC3 PC3/SPI0_NPCS0/PWML3/ISI_D11
*
* JP1 and JP2 seem to related to /CS on the Ronetix board, but the usage is
* less clear. For the Embest module, JP1 must be closed to connect /CS to
* PD13; on the Ronetix schematic, JP11 seems only to bypass a resistor (may
* not be populated?). I think closing JP1 is correct in either case.
* AT25_SPI0_NCPS0 goes to the AT25DF321A as via a NL17SZ126 if JP6 is closed
