The link_startup_again logic was added in Linux to handle device
that were set in LinkDown state, which should not be the case since U-boot
doesn't set LinkDown state are init, and Linux sets the device active
in ufshcd_init() for the first link startup.
ufshcd_set_ufs_dev_active(hba) is called at ufshcd_init() right before
scheduling an ufshcd_async_scan that will call ufshcd_device_init() then ufshcd_link_startup().
The comment in probe says:
/*
* We are assuming that device wasn't put in sleep/power-down
* state exclusively during the boot stage before kernel.
* This assumption helps avoid doing link startup twice during
* ufshcd_probe_hba().
*/
we can assume the same from U-Boot.
While it worked to far, it breaks link startup for Qualcomm Controllers v5,
let's just remove the logic.

There is no need to flush and invalidate all data updated by the
driver, mainly because on ARM platforms flush also invalidates
the cachelines.
Split the function in two and add the appropriate cacheline
invalidates after the UFS DMA operation finishes to make sure
we read from memory.
Flushing then invalidating cacheline unaligned data causes data
corruption issues on Qualcomm platforms, and is largely unnecessary
anyway, so let's cleanup the cache operations.

This module is a color active matrix LCD module incorporating
Oxide TFT (Thin Film Transistor). It is composed of a color TFT-LCD
panel, driver ICs, a control circuit and power supply circuit, and
a backlight unit. Graphics and texts can be displayed on a 2560×1600
dots panel with (16,777,216) colors by using MIPI DUAL DSI interface,
supplying +3.3V DC supply voltage for TFT-LCD panel driving and
supplying DC supply voltage for LED Backlight.

Tegra 3 has UART-E exposable via SD card slot which may be
handy for debugging. This change only adds funcmux part, to
use UART-E on the device you additionally would need:
- set stdout-path to serial@70006400 (uarte)
- configure sdmmc1_dat3_py4 and sdmmc1_dat2_py5 pinmux for
uarte
- disable or remove sdhci@7800000 node
- enable CONFIG_TEGRA_ENABLE_UARTE in defconfig
- set CFG_SYS_NS16550_COM to NV_PA_APB_UARTE_BASE in device

* Use f-string instead of formatting a regular string or using a

When OSCCA is enabled, FSB fuse shadow (offset 0x8000)
access is disabled for SOC. So update the driver to read fuse
from ELE API. The ELE has supported to read all shadow fuses like
FSB, reuse the table of FSB for the word index used by ELE API.
Add ELE shadow fuse read and write to current ELE fuse driver.
But when LC is OEM closed, the ELE read/write shadow fuse APIs are
forbidden. Reading from any fuse will return error. This causes
problem to u-boot which must read out some fuse no matter whatever LC.
So we have to change back to read from FSB and ELE common fuse read API.
For using ELE shadow read API for development purpose like checking
the ELE shadow fuse write result, user can set env variable
"enable_ele_shd" to y to switch it.

There is a bug when checking fuse word with redundancy fuse in FSB
table. The redundancy fuses are combined into 4 words, so we can't
directly use word index to do the check, otherwise the high 4 words
will fail to match.
And When calling ELE API, res parameter will pass to ELE API to get ELE
response value for failure. So most of usage does not initialize
this variable and print it after calling ELE API.
However, when ELE API returns failure, we can't ensure this res is
always set because there may be other failure like MU failure.
