b6b1b38a94 imx8mp_evk: Increase CONFIG_SYS_MALLOC_F_LEN
When booting imx8mp-evk the following allocation error
message is seen:

U-Boot 2021.01-rc3-00200-ge668bec96a5f (Dec 21 2020 - 14:36:42 -0300)

alloc space exhausted

Fix it by increasing CONFIG_SYS_MALLOC_F_LEN to 0x10000 like it
is done on other i.MX8MM/8MN boards.

717bf50f4b board: ge: bx50v3: cleanup phy config
The current PHY rework does the following things:

1. Configure 125MHz clock
2. Setup the TX clock delay (RX is enabled by default),
3. Setup reserved bits to avoid voltage peak

The clock delays are nowadays already configured by the
PHY driver (in ar803x_delay_config). The code for that
can simply be dropped. The clock speed can also be
configured by the PHY driver by adding the device tree
property "qca,clk-out-frequency".

What is left is setting up the undocumented reserved bits
to avoid the voltage peak problem. I slightly improved its
documentation while updating the board's PHY rework code.

db43c0b72d compiler.h: add host_build()
Add a host_build() function, so that it's possible to
check for software being build with USE_HOSTCC without
relying on preprocessor conditions. In other words

 #ifdef USE_HOSTCC
 	host_only_code();
 #endif

can be written like this instead:

 if (host_build())
 	host_only_code();

This improves code readability and test coverage and
compiler will eleminate this unreachable code.

247bbeb74c ARM: dts: imx8m: increase off-on delay on the SD Vcc regulator
Some SD Card controller and power circuitry has increased capacitance,
which keeps the internal logic remains powered after regulator is switch
off. This is generally the case when card is switched to SD104 mode,
where a power cycle should be performed. In case if the card internal
logic remains powered, it causes a subsequent failure of mode
transition, effectively leading to failed enumeration.

Introduce a delay of 20 msec in order to provide a possibility for
internal card circuitry to drain voltages and perform a power cycle
correctly.

Similar fix is done in commit c49d0ac38a ("ARM: dts: rmobile: Increase
off-on delay on the SD Vcc regulator") targeted Renesas SOCs.

fec7bf0460 spi: dw: Add mem_ops
The designware ssi device has "broken" chip select behaviour [1], and needs
specific manipulation to use the built-in chip select. The existing fix is
to use an external GPIO for chip select, but typically the K210 has SPI3
directly connected to a flash chip with dedicated pins. This makes it
impossible to use the spi_xfer function to use spi, since the CS is
de-asserted in between calls.  This patch adds an implementation of
exec_op, which gives correct behaviour when reading/writing spi flash.

This patch also rearranges the headers to conform to U-Boot style.

58875790fd spi: dw: Add support for multiple CTRLR0 layouts
CTRLR0 can have several different layouts depending on the specific device
(dw-apb-ssi vs dwc-ssi), and specific parameters set during synthesis.
Update the driver to support three specific configurations: dw-apb-ssi with
SSI_MAX_XFER_SIZE=16, dw-apb-ssi with SSI_MAX_XFER_SIZE=32, and dwc-ssi.

dw-apb-ssi is the version of the device on Altera/Intel SoCFPGAs, MSCC
SoCs, and Canaan Kendryte K210 SoCs. This is the only version this driver
supported before this change. The register layout before version 3.23a is:

|   31 .. 16  |
| other stuff |

|   15 .. 10  | 9 .. 8 | 7 .. 6 | 5 .. 4 | 3 .. 0 |
| other stuff |  TMOD  |  MODE  |  FRF   |  DFS   |

Note that DFS (Data Frame Size) is only 4 bits, limiting transfers to data
frames of 16 bits or less.

In version 3.23a, the SSI_MAX_XFER_SIZE parameter was introduced. This
parameter defaults to 16 (resulting in the same layout as prior versions),
but may also be set to 32. To allow setting longer data frame sizes, a new
DFS_32 register was introduced:

|   31 .. 21  | 20 .. 16 |
| other stuff |  DFS_32  |

|   15 .. 10  | 9 .. 8 | 7 .. 6 | 5 .. 4 |  3 .. 0   |
| other stuff |  TMOD  |  MODE  |  FRF   | all zeros |

The old DFS field no longer controls the data frame size. To detect this
layout, we try writing 0xF to DFS. If we read back 0x0, then this device
has SSI_MAX_XFER_SIZE=32.

dwc-ssi is the version of the device on Intel Keem Bay SoCs and Canaan
Kendryte K210 SoCs. The layout of ctrlr0 is:

|   31 .. 16  |
| other stuff |

|   15 .. 12  | 11 .. 10 | 9 .. 8 | 7 .. 6 | 4 .. 0 |
| other stuff |   TMOD   |  MODE  |  FRF   | DFS_32 |

The semantics of the fields have not changed since the previous version.
However, SSI_MAX_XFER_SIZE is effectively always 32.

To support these different layouts, we model our approach on the one
which the Linux kernel has taken. During probe, the driver calls an init
function stored in driver_data. This init function is responsible for
determining the layout of CTRLR0, and supplying the update_cr0 function.

The style of and information behind this commit is based on the Linux MMIO
driver for these devices. Specific reference was made to the series adding
support for Intel Keem Bay SoCs [1].

237e5880f8 spi: dw: Add SoC-specific compatible strings
This adds SoC-specific compatible strings to all users of the designware
spi device. This will allow for the correct driver to be selected for each
device. Where it is publicly documented, a compatible string for the
specific device version has also been added. Devices without
publicly-documented device versions include MSCC SoCs, and Arc Socs. All
compatible strings except those for SoCFPGAs and some of the versioned
strings have been taken from Linux.

Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly
necessary. However, it is a good cleanup and brings things closer to Linux.

caf110798c spi: dw: Fix driving MOSI low while recieving
The resting state of MOSI is high when nothing is driving it. If we drive
it low while recieving, it looks like we are transmitting 0x00 instead of
transmitting nothing. This can confuse slaves (like SD cards) which allow
new commands to be sent over MOSI while they are returning data over MISO.
The return of MOSI from 0 to 1 at the end of recieving a byte can look like
a start bit and a transmission bit to an SD card. This will cause the card
to become out-of-sync with the SPI device, as it thinks the device has
already started transmitting two bytes of a new command. The mmc-spi driver
will not detect the R1 response from the SD card, since it is sent too
early, and offset by two bits. This patch fixes transfer errors when using
SD cards with dw spi.

031b89e51b mtd: spinand: Do not erase the block before writing a bad block marker
Currently when marking a block, we use spinand_erase_op() to erase
the block before writing the marker to the OOB area. Doing so without
waiting for the operation to finish can lead to the marking failing
silently and no bad block marker being written to the flash.

In fact we don't need to do an erase at all before writing the BBM.
The ECC is disabled for raw accesses to the OOB data and we don't
need to work around any issues with chips reporting ECC errors as it
is known to be the case for raw NAND.

e6108004e6 mtd: spinand: Explicitly use MTD_OPS_RAW to write the bad block marker to OOB
When writing the bad block marker to the OOB area the access mode
should be set to MTD_OPS_RAW as it is done for reading the marker.
Currently this only works because req.mode is initialized to
MTD_OPS_PLACE_OOB (0) and spinand_write_to_cache_op() checks for
req.mode != MTD_OPS_AUTO_OOB.

Fix this by explicitly setting req.mode to MTD_OPS_RAW.

987f1e56ed mtd: spinand: Stop using spinand->oobbuf for buffering bad block markers
For reading and writing the bad block markers, spinand->oobbuf is
currently used as a buffer for the marker bytes. During the
underlying read and write operations to actually get/set the content
of the OOB area, the content of spinand->oobbuf is reused and changed
by accessing it through spinand->oobbuf and/or spinand->databuf.

This is a flaw in the original design of the SPI NAND core and at the
latest from 13c15e07eedf ("mtd: spinand: Handle the case where
PROGRAM LOAD does not reset the cache") on, it results in not having
the bad block marker written at all, as the spinand->oobbuf is
cleared to 0xff after setting the marker bytes to zero.

To fix it, we now just store the two bytes for the marker on the
stack and let the read/write operations copy it from/to the page
buffer later.
