There are two issues with the zeroing out code currently:
The cache flush does not take the zeroed out section into account!
The M4 firmware is started right after copying the firmware, and
might use the memory area. Since the M4 and the A7 (where U-Boot is
running) are not cache coherent, flushing cache could overwrite
the M4's variable at any point in time, leading to crashes of the
M4 firmware...
Secondly, the program header of a Cortex-M4 firmware might look like
this:
LOAD off 0x00007240 vaddr 0x20000240 paddr 0x1fffdcdc align 2**12
filesz 0x000001d0 memsz 0x000055c4 flags rw-
The code uses paddr as base, and zeros out everything which is
beyond file size. This might overlap into the next section! It
seems that memsz is in vaddr space and not paddr...
Since zeroing out is not strictly necessary (the firmwares C
initialization code should do that anyway) better play safe and
don't initialize the empty bytes...

The CR80 register has multiple interrupt bits, the code is supposed

The current mechanism using SCR/GPR registers work well when
the serial downloader boot mode has been selected explicitly
(either via boot mode pins or using bmode command). However,
in case the system entered boot ROM due to unbootable primary
boot devices (e.g. empty eMMC), the SPL fails to detect that
it has been downloaded through serial loader and tries to
continue booting from eMMC:
Trying to boot from MMC1
mmc_load_image_raw_sector: mmc block read error
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
The only known way to reliably detect USB serial downloader
is by checking the USB PHY receiver block power state...

Use i.MX bootaux support introduced for i.MX 6SoloX/i.MX 7 for
Vybrid too. Starting the Cortex-M4 core on Vybrid works a bit
differently, namely it uses a GPR register to define the initial
PC. There is no way to define the initial stack (the stack is
set up in a boot ROM). This is not a problem for most firmwares
since the firmwares startup code reinitialize the stack as part
of the firmware startup code anyway.

Support elf firmware files for the auxiliary Cortex-M4 core. This
has the advantage that the user does not need to know to which
address the binary has been linked to. However, in order to load
the elf sections to the right address, we need to translate the
Cortex-M4 core memory addresses to primary/host CPU memory
addresses (U-Boot is typically running on the A7/A9 core). This
allows to boot firmwares from any location with just using
bootaux, e.g.:
tftp ${loadaddr} low_power_demo.elf && bootaux ${loadaddr}

For i.MX 6SoloX/i.MX 7 simple binary files are used to boot the
auxiliary CPU core (Cortex-M4). This patch moves the "parsing" of
this binary firmwares to the SoC independent code. This allows to
add different binary formats more easily.
While at it, also move the comment about the inner workings how
to boot the Cortex-M4 core to a more appropriate location.

Before commit 81c4eccb55cc ("imx: mx6: fix USB bmode to use
reserved value") a non-reserved value has been used to trigger
Serial Downloader using bmode. On some boards this value lead to
unreliable bmode command. With the above mentioned commit, U-boot
switched to use [7:4] b0001, which translates to GPR9 0x10 for
Serial Downloader mode. Check for this new bmode and classify it
as Serial Downloader.

Add writebcb command which creates a NAND Boot Configuration Block
(BCB) at the beginning of the active flash device. The BCB stores
the information for the SoC internal boot ROM where the application
with a valid IVT header can be found on the NAND device. The first
two argument of the command need an offset of the NAND device where
the primary and secondary application can be found.
Typically, U-Boot is the application which gets loaded by the boot
ROM. Hence, the offset address need to be the address where U-Boot
(u-boot.imx along with a 0x400 long prefix) is stored on the device.
At least one location is mandatory.
Currently only the FCB (Firmware Configuration Block) is written to
the device. The DBBT (Discovered Bad Block Table) is optional and
not created by writebcb currently.

The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.
The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().

According PL310 TRM, Auxiliary Control Register
"
The register must be written to using a secure access, and it can be
read using either a secure or a NS access. If you write to this register
with a NS access, it results in a write response with a DECERR response,
and the register is not updated. Writing to this register with the L2
cache enabled, that is, bit[0] of L2 Control Register set to 1,
results in a SLVERR.
"
So If L2 cache is already enabled by ROM, chaning value of ACR
will cause SLVERR and uboot hang.
