518c5dfab0 power: pmic: Guard non-DM_PMIC drivers with a check for POWER_LEGACY
As we have more legacy PMIC drivers to move to Kconfig, guard them all
with POWER_LEGACY or SPL_POWER_LEGACY. Do the same kind of check for
building the drivers too. This also means that we need to resort the
list slightly in the Makefile.

e23544cffe net: xilinx_axi: add PCS/PMA PHY
If we bridge an external PHY to Xilinx's PCS/PMA PHY and would like to
get and set the real status of the PHY facing the external world. Then
we should phy_connect() to the external PHY instead of the PCS/PMA one.
Thus, we add a pcs-handle DT entry, which have been merged in Linux, and
leave the configuration of it to the driver itself.

Unlike Linux, where the PCS/PMA PHY is managed by phylink, managing the
PCS/PMA PHY is only internal to the driver in U-Boot. The PCS/PMA PHY
pressents only when the phy-mode is configured as SGMII or 1000Base-X,
so it is always 1 Gbps and full-duplex and we may skip passing link
information out.

dec64d55af dm: core: Fix iteration over driver_info records
We should only perform additional iteration steps when needed to
initialize the parent of a device. Other binding errors (such as a
missing driver) should not lead to additional iteration steps.

Unnecessary iteration steps can cause issues when memory is tightly
constrained (such as in the TPL/SPL) since device_bind_by_name()
unconditionally allocates memory for a struct udevice. On the SanCloud
BBE this led to boot failure caused by memory exhaustion in the SPL
when booting from SPI flash.

d1559435d7 net: macb: Fix race caused by flushing unwanted descriptors
The rx descriptor list is in cached memory, and there may be multiple
descriptors per cache-line. After reclaim_rx_buffers marks a descriptor
as unused it does a cache flush, which causes the entire cache-line to
be written to memory, which may override other descriptors in the same
cache-line that the controller may have written to.

The fix skips freeing descriptors that are not the last in a cache-line,
and if the freed descriptor is the last one in a cache-line, it marks
all the descriptors in the cache-line as unused.
This is similarly to what is done in drivers/net/fec_mxc.c

In my case this bug caused tftpboot to fail some times when other
packets are sent to u-boot in addition to the ongoing tftp (e.g. ping).
The driver would stop receiving new packets because it is waiting
on a descriptor that is marked unused, when in reality the descriptor
contains a new unprocessed packet but while freeing the previous buffer
descriptor & flushing the cache, the driver accidentally marked the
descriptor as unused.

e9d3fc7e46 net: dwc_eth_qos: Add support for bulk RX descriptor cleaning
Add new desc_per_cacheline property which lets a platform run RX descriptor
cleanup after every power-of-2 - 1 received packets instead of every packet.
This is useful on platforms where (axi_bus_width EQOS_AXI_WIDTH_n * DMA DSL
inter-descriptor word skip count + DMA descriptor size) is less than cache
line size, which necessitates packing multiple DMA descriptors into single
cache line.

In case of TX descriptors, this is not a problem, since the driver always
does synchronous TX, i.e. the TX descriptor is always written, flushed and
polled for completion in eqos_send().

In case of RX descriptors, it is necessary to update their status in bulk,
i.e. after the entire cache line worth of RX descriptors has been used up
to receive data.

c55ac51a55 usb: dwc3: Program GFLADJ
GUCTL.REFCLKPER can only account for clock frequencies with integer
periods. To address this, program REFCLK_FLADJ with the relative error
caused by period truncation. The formula given in the register reference
has been rearranged to allow calculation based on rate (instead of
period), and to allow for fixed-point arithmetic.

Additionally, calculate a value for 240MHZDECR. This configures a
simulated 240Mhz clock using a counter with one fractional bit (PLS1).

This register is programmed only for versions >= 2.50a, since this is
the check also used by commit db2be4e9e30c ("usb: dwc3: Add frame length
adjustment quirk").

bd1e195421 ram: ast2600: Improve ddr4 timing and signal quality
Adjust the following settings to get better timing and signal quality.

1. write DQS/DQ delay
- 1e6e2304[0]
- 1e6e2304[15:8]

2. read DQS/DQ delay
- 0x1e6e0298[0]
- 0x1e6e0298[15:8]

3. CLK/CA timing
- 0x1e6e01a8[31]

4. Read and write termination
- change RTT_ROM from 40 ohm to 48 ohm (MR1[10:8])
- change RTT_PARK from disable to 48 ohm (MR5[8:6])
- change RTT_WR from 120 ohm to disable (MR2[11:9])
- change PHY ODT from 40 ohm to 80 ohm (0x1e6e0130[10:8])

Note1: Both DDR-PHY and DDR controller have their own registers for DDR4
Mode Registers (MR0~MR6).  This patch introduces macros to synchronize
the MR value on both sides.

Note2: the waveform meansurement can be found in item #21 of Aspeed
AST26x0 Application note (AP note).

581df347db ram: ast2600: Fix incorrect statement of the register polling
The condition "~data" in the if-statement is a typo.  The original
intention is to poll if SDRAM_PHYCTRL0_INIT bit equals to 0. So use
"data == 0" for instead.

Besides, the bit[1] of "phy_status" register is hardwired to
SDRAM_PHYCTRL0_INIT (with inverse logic). Since SDRAM_PHYCTRL0_INIT has
already done, remove the unnecessary checking of phy_status[1].

When cadence_qspi_versal_flash_reset() function is called in mini
u-boot where there is no firmware support, it is missing defines for
macro's BOOT_MODE_POR_0 & BOOT_MODE_POR_1. Remove them and replace with
already define macro's which have same values as these.
