f3d235702d mtd: nand: pxa3xx: Fix READOOB implementation
In the current driver, OOB bytes are accessed in raw mode, and when a
page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the
driver must read the whole spare area (64 bytes in case of a 2k page,
16 bytes for a 512 page). The driver was only reading the free OOB
bytes, which was leaving some unread data in the FIFO and was somehow
leading to a timeout.

We could patch the driver to read ->spare_size + ->ecc_size instead of
just ->spare_size when READOOB is requested, but we'd better make
in-band and OOB accesses consistent.
Since the driver is always accessing in-band data in non-raw mode (with
the ECC engine enabled), we should also access OOB data in this mode.
That's particularly useful when using the BCH engine because in this
mode the free OOB bytes are also ECC protected.

b47f677931 mtd: nand: pxa3xx_nand: add support for partial chunks
This commit is needed to properly support the 8-bits ECC configuration
with 4KB pages.

When pages larger than 2 KB are used on platforms using the PXA3xx
NAND controller, the reading/programming operations need to be split
in chunks of 2 KBs or less because the controller FIFO is limited to
about 2 KB (i.e a bit more than 2 KB to accommodate OOB data). Due to
this requirement, the data layout on NAND is a bit strange, with ECC
interleaved with data, at the end of each chunk.

When a 4-bits ECC configuration is used with 4 KB pages, the physical
data layout on the NAND looks like this:

| 2048 data | 32 spare | 30 ECC | 2048 data | 32 spare | 30 ECC |

So the data chunks have an equal size, 2080 bytes for each chunk,
which the driver supports properly.

When a 8-bits ECC configuration is used with 4KB pages, the physical
data layout on the NAND looks like this:

| 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 1024 data | 30 ECC | 64 spare | 30 ECC |

So, the spare area is stored in its own chunk, which has a different
size than the other chunks. Since OOB is not used by UBIFS, the initial
implementation of the driver has chosen to not support reading this
additional "spare" chunk of data.

Unfortunately, Marvell has chosen to store the BBT signature in the
OOB area. Therefore, if the driver doesn't read this spare area, Linux
has no way of finding the BBT. It thinks there is no BBT, and rewrites
one, which U-Boot does not recognize, causing compatibility problems
between the bootloader and the kernel in terms of NAND usage.

To fix this, this commit implements the support for reading a partial
last chunk. This support is currently only useful for the case of 8
bits ECC with 4 KB pages, but it will be useful in the future to
enable other configurations such as 12 bits and 16 bits ECC with 4 KB
pages, or 8 bits ECC with 8 KB pages, etc. All those configurations
have a "last" chunk that doesn't have the same size as the other
chunks.

In order to implement reading of the last chunk, this commit:

 - Adds a number of new fields to the pxa3xx_nand_info to describe how
   many full chunks and how many chunks we have, the size of full
   chunks and partial chunks, both in terms of data area and spare
   area.

 - Fills in the step_chunk_size and step_spare_size variables to
   describe how much data and spare should be read/written for the
   current read/program step.

 - Reworks the state machine to accommodate doing the additional read
   or program step when a last partial chunk is used.

b87ae6f587 mtd: pxa3xx_nand: Fix initial controller configuration
The Data Flash Control Register (NDCR) contains two types
of parameters: those that are needed for device identification,
and those that can only be set after device identification.

Therefore, the driver can't set them all at once and instead
needs to configure the first group before nand_scan_ident()
and the second group later.

Let's split pxa3xx_nand_config in two halves, and set the
parameters that depend on the device geometry once this is known.

6bbe7f681f mtd: pxa3xx_nand: Increase the initial chunk size
The chunk size represents the size of the data chunks, which
is used by the controllers that allow to split transferred data.

However, the initial chunk size is used in a non-split way,
during device identification. Therefore, it must be large enough
for all the NAND commands issued during device identification.
This includes NAND_CMD_PARAM which was recently changed to
transfer up to 2048 bytes (for the redundant parameter pages).

Thus, the initial chunk size should be 2048 as well.

On Armada 370/XP platforms (NFCv2) booted without the keep-config
devicetree property, this commit fixes a timeout on the NAND_CMD_PARAM
command:

4b8cb84327 phy: marvell: Support changing SERDES map in board file
This adds a weak definition of comphy_update_map to comphy_core,
which does nothing. If this function is defined elsewhere, for example
in board file, the board file can change some parameters of SERDES
configuration.

This is needed on Turris Mox, where the SERDES speed on lane 1 has to
be set differently when SFP module is connected and when Topaz Switch
module is connected.

This is a temporary solution. When the comphy driver for armada-3720
will be added to the kernel, the comphy driver in u-boot shall also be
updated and this should be done differently then.

blindly shifted by the number of the gpio.  This worked for gpio

The strobe dll code is ported from Linux Kernel:

The comments are from the above file,
"For HS400 eMMC, there is a data_strobe line. This signal is generated
by the device and used for data output and CRC status response output
in HS400 mode. The frequency of this signal follows the frequency of
CLK generated by host. The host receives the data which is aligned to the
edge of data_strobe line. Due to the time delay between CLK line and
data_strobe line, if the delay time is larger than one clock cycle,
then CLK and data_strobe line will be misaligned, read error shows up.
So when the CLK is higher than 100MHz, each clock cycle is short enough,
host should configure the delay target. "

of the VPU and VAPB clocks configured from DT using assigned-clocks entries.

dee37fc99d Remove <inttypes.h> includes and PRI* usages in printf() entirely
In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's <inttypes.h>.
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

69f78cf840 watchdog: mx25: use the imx_watchdog driver for mx25
The existing imx_watchdog driver is compatible with mx25 chipsets.
Add a WDOG1_BASE_ADDR define for the base address and enable the driver
in watchdog's Makefile.

To use the driver, a board must define CONFIG_IMX_WATCHDOG and
CONFIG_HW_WATCHDOG.

This fixes an issue when booting an mx25 chip via usb/serial. In this
case, the boot rom will always enable the watchdog. If u-boot is running
in interactive mode and the watchdog is not serviced, the system is
rebooted when the watchdog expires.

1a35526e1d usb: musb-new: omap2430: Enable DM_USB and OF support
With upcoming changes that require CONFIG_BLK, this broke
USB Mass Storage on the OMAP3 boards because if CONFIG_BLK is
enabled, it assumes that DM_USB is enabled, but it wasn't yet
available on omap3 and omap4 boards.

This patch converts the OMAP2430 MUSB glue to support DM_USB and
extracts the necessary information based on the device tree.

It's based on the ti-musb driver, but there are enough significant
differences in both the architecture and device tree entires between
am33xx and OMAP3/OMAP4, that I think it makes sense to continue to
keep the separate.

Per doc/driver-model/usb-info.txt, the USB gadget stuff hasn't
migrated to DM_USB yet, so this only supports USB Host for now.

Users wanting USB Gadgets will need to disable DM_USB and leave
it the old way for now.

46703cd9f3 tpm: sandbox: fix wrong assignment with a simplification
The recv variable in sandbox_tpm2_fill_buf() is a pointer on a pointer
of a char array. It means accessing *recv is the char array pointer
itself while **recv is the first character of that array. There is no
need for such indirection here, so simplify the code.

Simplifying things will make the last assignment right: "*recv = NULL"
is now correct. The issue has been found by the following Coverity
Scan report:

    CID 183371:  Incorrect expression  (UNUSED_VALUE)
    Assigning value "4UL" to "*recv" here, but that stored value is overwritten before it can be used.
    232             *recv += sizeof(rc);
    233
    234             /* Add trailing \0 */
    235             *recv = NULL;

While at simplifying things, use '\0' instead of NULL when adding an
empty char at the end of the buffer.

fd973ca696 tpm: sandbox: fix wrong check on pcr_map
The second check on pcr_map in sandbox_tpm2_xfer() is wrong. It should
check for pcr_map not being empty. Instead, it is a pure copy/paste of
the first check which is redundant.

This has been found thanks to a Coverity Scan report:

    CID 183370:  Memory - illegal accesses  (UNINIT)
    Using uninitialized value "pcr_index".
        put_unaligned_be32(tpm->pcr_extensions[pcr_index], recv);

This is because pcr_index is initialized only if the user input is
correct, ie. at least one valid bit is set in pcr_map.

Fix the second check and also initialize pcr_index to 0 (which is
harmless in case of error) to make Coverity Scan happy.

1711add3dc mtd: nand: fsl_ifc: Fix handling of bitflips in erased pages
This is a fix made for the fsl_ifc_nand driver on linux kernel by
Pavel Machek and is applied to uboot. It is currently on applied on
linux-mtd.

https://patchwork.kernel.org/patch/9758117/

IFC always raises ECC errors on erased pages. It is only ignored when
the buffer is checked for all 0xFF by is_blank(). The problem is a
single bitflip will cause is_blank() and then mtd_read to fail. The fix
makes use of nand_check_erased_ecc_chunk() to check for empty pages
instead of is_blank(). This also makes sure that reads are made at ECC
page size granularity to get a proper bitflip count. If the number of
bitflips does not exceed the ECC strength, the page is considered empty
and the bitflips will be corrected when data is sent to the higher
layers (e.g. ubi).

feaa7856f5 dfu: Fix data abort in dfu_free_entities()
Commit 5d8fae7916 ("dfu: avoid memory leak") brings a regression which
described below. This patch is effectively reverting that commit, adding
corresponding comment to avoid such regressions in future.

In case of error in dfu_config_entities(), it frees "dfu" array, which
leads to "data abort" in dfu_free_entities(), which tries to free the
same array (and even tries to access it from linked list first). The
issue occurs e.g. when partition table on device does not match
$dfu_alt_info layout:

    => dfu 0 mmc 1
    Couldn't find part #2 on mmc device #1
    DFU entities configuration failed!
    data abort

To fix this issue, do not free "dfu" array in dfu_config_entities(). It
will be freed later in dfu_free_entities().

Tested on BeagleBone Black (where this regression was originally found).

11758a56ab usb: rockchip: be quiet on serial port while transferring data
While downloading or uploading megabytes of data we had thousands of
printf in console like:

transfer 0x10000 bytes done
OR
Uploading 0x1000 bytes

This because transfers are chunked and there is no way on target
side to know the overall transfer size (to print one string per
overall transfer).

All these prints on serial console do slow down significantly the
transfer and does not offer a significant information to the
developer: rkdeveloptool and Rockchip original tool do use small
chunks read/writes on big transfers. This allows on workstation
to print percentage of transfer complete and as well offers to
developer the information about: transfer is running OK.
On error, either the percentage will stop or an error will be shown
on workstation console.

cad66e324d usb: rockchip: fix command failed on host side due to missing data
Two consecutive rockusb_tx_write without waiting for request complete
do results in transfer reset of first request and thus no or incomplete
data transfer. This because rockusb_tx_write do use just one USB request
to keep serialization.

So calls like:
rockusb_tx_write_str(emmc_id);
rockusb_tx_write_csw(cbw->tag, cbw->data_transfer_length, CSW_GOOD);

was succeeding only when DEBUG was defined because the time spent
printing debug info was enough for transfer to complete.

This patch fixes the issue adding a simple request complete handler
called rockusb_tx_write_csw to be set as complete handler of in_req
when sending back simple payload + CSW replies to commands.

This new handler will always send CSW_GOOD replies because in case
of error the command callback itself must send back an error CSW as
unique reply to command.

This patch fixes execution of:
$ rkdeveloptool rfi
when DEBUG is not defined.

The bug only shows up when bus number is not equal to zero. This is
caused by the plain find_devfn parameter is passed to function call
pci_bus_find_devfn(), inside which find_devfn is compared to devfn
in the device's pplat structure. However pplat->devfn does not carry
the bus number. Fix this by passing find_devfn with bus number masked.

By convention for DM_MMC the host->priv is used to store struct udevice
*dev pointer.

Unfortunately, the legacy Exynos DW MMC code uses this field to
store pointer to dwmci_exynos_priv_data struct
Hence, we do need to get data in other way - namely by using container_of
when host pointer is present.
In this way the sdr_timing data is properly accessed.

fe3eb7a887 GPIO: CREG: improve flexibility of hsdk-creg-gpio driver
CREG GPIO is a driver for weird soc-specific output ports, which are
controlled by some fields in memory mapped register.

Example:

31                 9        7        5           0   < bit number
|                  |        |        |           |
[     not used     | gpio-1 | gpio-0 | <-shift-> ]   < 32 bit register
                       ^        ^
                       |        |
                write 0x2 == set output to "1" (activate)
                write 0x3 == set output to "0" (deactivate)

As of tooday we only support fixed (hardcoded) bit per gpio line,
activate / deactivatei and shift values. Fix that by read them from
device tree to be able to use this driver for other boards.

Remove "hsdk" prefix from compatible string as this driver can be
used with different boards like HSDK, AXS101, AXS103, etc.

2a2096ea60 tpm: allow TPM v1 and v2 to be compiled at the same time
While there is probably no reason to do so in a real life situation, it
will allow to compile test both stacks with the same sandbox defconfig.

As we cannot define two 'tpm' commands at the same time, the command for
TPM v1 is still called 'tpm' and the one for TPM v2 'tpm2'. While this
is the exact command name that must be written into eg. test files, any
user already using the TPM v2 stack can continue to do so by just writing
'tpm' because as long as TPM v1 support is not compiled, U-Boot prompt
will search for the closest command named after 'tpm'.

The command set can also be changed at runtime (not supported yet, but
ready to be), but as one can compile only either one stack or the other,
there is still one spot in the code where conditionals are used: to
retrieve the v1 or v2 command set.

eef0b8a930 net: phy: add ofnode node to struct phy_device
Now the UCLASS_ETH device "node" field is owerwritten by some network drivers in
case of Ethernet PHYs which are linked to UCLASS_ETH device using
"phy-handle" DT property and when Ethernet PHY driver needs to read some
additional information from DT. In such cases following happens (in
general):

- network drivers
	priv->phydev = phy_connect(priv->bus, priv->phyaddr, dev,
				   priv->interface);
	<-- phydev is connected to dev which is UCLASS_ETH device

	if (priv->phy_of_handle > 0)
		dev_set_of_offset(priv->phydev->dev, priv->phy_of_handle);
	<-- phydev->dev->node is overwritten by phy-handle DT node

- PHY driver in .config() callback
	int node = dev_of_offset(dev);
	<-- PHY driver uses overwritten dev->node
        const void *fdt = gd->fdt_blob;

	 if (fdtdec_get_bool(fdt, node, "property"))
		...

As result, UCLASS_ETH device can't be used any more for DT accessing.

This patch adds additional ofnode node field to struct phy_device which can
be set explicitly by network drivers and used by PHY drivers, so
overwriting can be avoided. Also add helper function phy_get_ofnode()
which will check and return phy_device->node or dev_ofnode(phydev->dev) for
backward compatibility with existing drivers.

63d3192984 net: phy: dp83867: add workaround for incorrect RX_CTRL pin strap
The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
supported (see note below Table 5 (4-Level Strap Pins)).

It further advises that if a board has this pin strapped in mode 1 and
mode 2, then bit[7] of Configuration Register 4 (address 0x0031) must
be cleared to 0. This is to ensure proper operation of PHY.

Since it is not possible to detect in software if RX_DV/RX_CTRL pin is
incorrectly strapped, add a device-tree property to advertise this and
allow corrective action in software.

b19886b946 ARM: qemu-arm: enable RTC
QEMU provides an emulated ARM AMBA PrimeCell PL031 RTC.

The patch sets the base address in the board include file according to the
definition in hw/arm/virt.c of the QEMU source. It defines the Kconfig
option for the existing driver, and enables the RTC driver in
qemu_arm64_defconfig and qemu_arm_defconfig as well as the date command.

We need an RTC to provide the GetTime() runtime service in the UEFI
subsystem.

844f9bf1ee power: regulator: stpmu1: add power off delay
This patch adds a delay when regulators are disabled.
This delay is set to 5 ms to cover all use cases.
The worst use case actually seen is during a SD card power cycle.

a1b2faed7c phy: Be able to get phy from PHY provider
In case of phy are provided from a PHY provider nodes as following:

usbphyc: usb-phy@5a006000 {
	compatible = "st,stm32mp1-usbphyc";
	reg = <0x5a006000 0x1000>;
	clocks = <&rcc_clk USBPHY_K>;
	resets = <&rcc_rst USBPHY_R>;
	#address-cells = <1>;
	#size-cells = <0>;

	usbphyc_port0: usb-phy@0 {
		reg = <0>;
		phy-supply = <&vdd_usb>;
		vdda1v1-supply = <&reg11>;
		vdda1v8-supply = <&reg18>
		#phy-cells = <0>;
	};

	usbphyc_port1: usb-phy@1 {
		reg = <1>;
		phy-supply = <&vdd_usb>;
		vdda1v1-supply = <&reg11>;
		vdda1v8-supply = <&reg18>
		#phy-cells = <1>;
	};
};

and PHY are called as following:

usbh_ehci: usbh-ehci@5800d000 {
	compatible = "generic-ehci";
	reg = <0x5800d000 0x1000>;
	clocks = <&rcc_clk USBH>;
	resets = <&rcc_rst USBH_R>;
	interrupts = <GIC_SPI 75 IRQ_TYPE_NONE>;
	companion = <&usbh_ohci>;
	phys = <&usbphyc_port0>;
	phy-names = "usb";
	status = "okay";
};

generic_phy_get_by_index() must be updated to first look for
PHY phandle as previously and in case of error looks for PHY
provider by finding the parent's current node which is the PHY
provider.
args (ofnode_phandle_args struct) must also be updated by inserting
the phy index into the PHY provider as args[0].

7d118161bb mmc: stm32_sdmmc2: update pwron management
Correctly manage the SDMMC reset and card cycle power
to fully handle the power cycle added in the MMC uclass
and avoid issue with level-shifter with some uSDCARD.

3 states managed in driver:
  1/ reset: SDMMC disable, signal HiZ
  2/ power-cycle: SDMMC disable, signals drive to 0
  3/ power-on: SDMMC enabled

0bd83060c2 watchdog: cadence: Do not stop wdt in probe
Watchdog can be started before probe and u-boot should just take control
over it. That's why do not stop watchdog in probe to cover cases where
watchdog can expire before probe and start.

6c253be7ce watchdog: cdns: Add comment for expire_now function
IP itself has no reg/no bit which can be used for this functionality.
Add this note to the driver to make sure that none will be asking for
that. Current method is to setup 1s timeout and hang() which is done via
wdt_expire_now().

4a69366967 microblaze: Convert generic platform to DM gpio
Converting GPIO to DM requires to do changes in reset subsystem
that's why support for Microblaze soft reset via sysreset and GPIO
sysreset support was added.
These two patches enables enabling GPIO DM.
Microblaze soft reset is bind at last reset method.

GPIO reset is handled via sysreset with adding this fragment to DT.

gpio-restart {
	compatible = "gpio-restart";
	gpios = <&reset_gpio 0 0 0>;
	/* 3rd cell ACTIVE_HIGH = 0, ACTIVE_LOW = 1 */
};

hard-reset-gpio property is not documented and also handled.
Conversion is required.

Unfortunately do_reset is required for SPL that's why use only soft
microblaze reset for now.
