Revert "rockchip: Only call binman when TPL available"
This reverts commit
f5315dd6290a588434e4f79bfd2886bb7df9210d.
[why]
TPL is not mandatory for not all Rockchip SoCs, some SoCs like
RK356x, and RK3588 still use mainline u-boot without TPL as
their ddr init programs are accessed via binaries provided by
Rockchip instead of ddr source code.
Marking TPL build makes it not able to build u-boot.itb on
RK356x targets so revert this so that it can build an SPL build
that would support all across Rockchip platforms.

Merge branch '2023-01-27-apple-soc-updates'
First, to quote the author:
This series adds support for the PCIe controller found on Apple M1 and
M2 machines and enables support for PCIe XHCI controllers. This makes
the type-A USB ports on the M1 Mac mini work. Since the use of Apples
DART IOMMU is mandatory (these PCIe DARTs don't support bypass mode),
this adds DMA mapping operations to the IOMMU uclass and implements
them for the Apple DART. It modifies the XHCI driver code to go map
DMA buffers through the IOMMU if there is one. Since the M1 Mac mini
now has two types of XHCI controllers with different number of ports
(2 for the DWC3 controllers, 8 for the Fresco Logic PCIe controller)
this uncovered an issue in with the way the hub descriptor is
implemented in the XHCI driver.
Second, Mark also fixes some Apple-specific instances of
CONFIG_IS_ENABLED that should be IS_ENABLED.

mkimage: fit: Support signed configurations in 'auto' FITs
Extend support for signing in auto-generated (-f auto) FIT. Previously,
it was possible to get signed 'images' subnodes in the FIT using
options -g and -o together with -f auto. This patch allows signing
'configurations' subnodes instead of 'images' ones (which are hashed),
using option -f auto-conf instead of -f auto. Adding also -K <dtb> and
-r options, will add public key to <dtb> file with required = "conf"
property.
Summary:
-f auto => FIT with crc32 images
-f auto -g ... -o ... => FIT with signed images
-f auto-conf -g ... -o ... => FIT with sha1 images and signed confs
Example: FIT with kernel, two device tree files, and signed
configurations; public key (needed to verify signatures) is
added to u-boot.dtb with required = "conf" property.
mkimage -f auto-conf -A arm -O linux -T kernel -C none -a
43e00000 \
-e 0 -d vmlinuz -b /path/to/first.dtb -b /path/to/second.dtb \
-k /folder/with/key-files -g keyname -o sha256,rsa4096 \
-K u-boot.dtb -r kernel.itb
Example: Add public key with required = "conf" property to u-boot.dtb
without needing to sign anything. This will also create a useless FIT
named unused.itb.

The 0xC1 can be used in two cases.
1. Char record type 8-bit ASCII + Latin 1 with length of 1.
(For example board revision 'A')
2. C1h (type/length byte encoded to indicate no more info fields).

"ASCII+LATIN1" is defined as the printable characters from the
first set of 256 characters of Unicode 6.2 (U+0000h through U+00FFh,

net: zynq_gem: Wait for SGMII PCS link in zynq_gem_init()
In our system using ZynqMP with an external SGMII PHY it's necessary
to wait for the PCS link and auto negotiation to finish before the xfer
starts. Otherwise the first packet(s) might get dropped, resulting in a
delay at the start of the ethernet transfers.
This is only done when the PHY link is already up, which is done in
phy_startup(). As waiting for the PHY link bits via pcsstatus does not
make much sense, when the link is not available in general (e.g. no
cable connected).
This patch adds the necessary code including a minimal delay of 1 ms
which fixes problems of dropped first packages.

SPL load FIT images by reading the data aligned to block length.

Unaligned image data is written to an offset of the load address and

This adds a small overhead of having to memcpy unaligned data, something
that normally is not an issue.
However, TF-A may have a segment that should be loaded into SRAM, e.g.
vendor TF-A for RK3568 has a 8KiB segment that should be loaded into the

cmd: simplify do_spi_flash()
CMD_RET_USAGE == -1. The special handling of this value at the end of
do_spi_flash() does not make any sense.
To avoid future confusion use the CMD_RET_* constants and simplify the
code.

cmd: fix return code of 'sf write' and 'sf read'
If the offset or the size passed to the 'sf write' or 'sf read' command
exceeds the size of the SPI flash displaying the command usage is not
helpful. Return CMD_RET_FAILURE instead of CMD_RET_USAGE.
Use the CMD_RET_* constants instead of 0, 1, -1.

spi: cadence_qspi: use STIG mode for small reads
Fix the issue where some flash chips like cypress S25HS256T return the
value of the same register over and over in DAC mode.
For example in the TI K3-AM62x Processors refer [0] Technical Reference
Manual there is a layer of digital logic in front of the QSPI/OSPI
Drive when used in DAC mode. This is part of the Flash Subsystem (FSS)
which provides access to external Flash devices.
The FSS0_0_SYSCONFIG Register (Offset = 4h) has a BIT Field for
OSPI_32B_DISABLE_MODE which has a Reset value = 0. This means, OSPI 32bit
mode enabled by default.
Thus, by default controller operates in 32 bit mode causing it to always
align all data to 4 bytes from a 4byte aligned address. In some flash
chips like cypress for example if we try to read some regs in DAC mode
then it keeps sending the value of the first register that was requested
and inorder to read the next reg, we have to stop and re-initiate a new
transaction.
This causes wrong register values to be read than what is desired when
registers are read in DAC mode. Hence if the data.nbytes is very less
then prefer STIG mode for such small reads.

spi: cadence_qspi: setup ADDR Bits in cmd reads
Setup the Addr bit field while issuing register reads in STIG mode. This
is needed for example flashes like cypress define in their transaction
table that to read any register there is 1 cmd byte and a few more address
bytes trailing the cmd byte. Absence of addr bytes will obviously fail
to read correct data from flash register that maybe requested by flash
driver because the controller doesn't even specify which address of the
flash register the read is being requested from.

mtd: spi-nor-core: Make CFRx reg fields generic
Cypress defines two flavors of configuration registers, volatile and
non volatile, and both use the same bit fields. Rename the bitfields in
the configuration registers so that they can be used for both flavors.

CFR5[6] is reserved bit and must be always 1. Set it to comply with flash

stop using magic numbers and describe the missing bit fields in CFR5
