MTD: mxs_nand_spl: Redo the way nand_init initializes
Currently the spl system calls nand_init which does nothing.
It isn't until an attempt to load from NAND that it gets initialized.
Subsequent attempts to load just skip the initialization because
NAND is already initialized.
This moves the contents of mxs_nand_init to nand_init. In the event
of an error, it clears the number of nand chips found. Any
attempts to use nand will check if there are nand chips available
instead of actually doing the initialization at that time. If there
are none, it will return an error to the higher level calls.

ARM: dts: rmobile: Zap redundant USB/SDHI nodes on M3N
v2019.01 commit
cbff9f80cedd ("ARM: dts: rmobile: Sync Gen3 DTs with
Linux 4.19.6") made the sdhi/usb nodes available in r8a77965.dtsi.
Hence, remove the SDHI/USB nodes from r8a77965-u-boot.dtsi. This is
equivalent to partially reverting below v2019.01 commits:
-
f529bc551b6d ("ARM: dts: rmobile: Extract USB nodes on M3N")
-
830b94f76867 ("ARM: dts: rmobile: Extract SDHI nodes on M3N")
Duplicating the nodes from <soc>.dtsi to <soc>-u-boot.dtsi is obviously:
- not needed if no U-boot-specific changes are needed in those nodes.
- potentially dangerous/error-prone, since the duplicated properties
override the properties originally defined in <soc>.dtsi. One
possible consequence is that <soc>.dtsi is getting an update from
Linux, while <soc>-u-boot.dtsi stays unchanged. In this situation,
the obsolete property values from <soc>-u-boot.dtsi will take
precedence masking some of the <soc>.dtsi updates, potentially
leading to all kind of obscure issues.
Below is the dtdiff of r8a77965-salvator-x-u-boot.dtb (the only "user"
of r8a77965-u-boot.dtsi) before and after the patch (slightly
reformatted to avoid 'git am/apply' issues and to reduce the width).
What below output means is there is already a mismatch in some of
SDHI/USB nodes between r8a77965.dtsi and r8a77965-u-boot.dtsi. Since no
U-Boot customization is needed in SDHI/USB DT nodes, get rid of them in
r8a77965-u-boot.dtsi.

spi: sun4i: Poll for rxfifo to be filled up
To drain rx fifo the fifo need to poll for how much data has
been filled up in rx fifo.
To achieve this, the current code is using wait_for_bit logic
on control register with exchange burst mode mask, which is not
a proper way of waiting for fifo filled up.
So, add code for polling rxfifo to be filled up using fifo
status register.
