is used for example on NXP imx8mm EVK.
Add regulator driver for ROHM BD71837 and BD71847 PMICs.
BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced
version containing 6 bucks and 6 LDOs. Voltages for DVS
bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted
when regulators are enabled. For other bucks and LDOs we may
have over- or undershooting if voltage is adjusted when
regulator is enabled. Thus this is prevented by default.
BD718x7 has a quirk which may leave power output disabled
after reset if enable/disable state was controlled by SW.
Thus the SW control is only allowed for BD71837 bucks
3 and 4 by default. The impact of this limitation must be
evaluated board-by board and restrictions may need to be
modified. (Linux driver get's these limitations from DT and we
may want to implement same on u-Boot driver).

Writing/updating boot image in nand device is not
straight forward in i.MX6 platform and it requires
boot control block(BCB) to be configured.
It becomes difficult to use uboot 'nand' command to
write BCB since it requires platform specific attributes
need to be taken care of.
It is even difficult to use existing msx-nand.c driver by
incorporating BCB attributes like mxs_dma_desc does
because it requires change in mtd and nand command.
So, cmd_nandbcb implemented in arch/arm/mach-imx
BCB contains two data structures, Firmware Configuration Block(FCB)
and Discovered Bad Block Table(DBBT). FCB has nand timings,
DBBT search area, page address of firmware.
On summary, nandbcb update will
- erase the entire partition
- create BCB by creating 2 FCB/DBBT block followed by
1 FW block based on partition size and erasesize.
- fill FCB/DBBT structures
- write FW/SPL on FW1
- write FCB/DBBT in first 2 blocks
for nand boot, up on reset bootrom look for FCB structure in
first block's if FCB found the nand timings are loaded for
further reads. once FCB read done, DTTB will load and finally
firmware will be loaded which is boot image.

The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the

2) Check for presence of daughter card(s) by probing the associated

In order to be able to use more advanced driver functionality which often

several things need to be in place:
1) Memory needs to be available for BSS to use. For this, we locate BSS
at the top of the MCU SRAM area, with the stack starting right below
it,
2) We need to move the initialization of BSS prior to entering
board_init_f(). We will do this with a separate commit by turning on

In this commit we also clean up the assignment of the initial SP address
as part of the refactoring, taking into account the pre-decrement post-
