<title>treewide: use dev_read_addr_*_ptr() where appropriate</title>

<id>5fecea171de3b66e9e3a199c588bf12c6b1d3084</id>
<content type='text'>
A follow-up to commit 842fb5de424e
("drivers: use devfdt_get_addr_size_index_ptr when cast to pointer")
and commit 320a1938b6f7
("drivers: use devfdt_get_addr_index_ptr when cast to pointer").

In addition to using the *_ptr variants of these functions where the
address is cast to a pointer, this also changes devfdt_get_addr_*() to
dev_read_addr_*() in a few places. Some variable and field types are
changed from fdt_addr_t or phys_addr_t to void* where the cast was
happening later.

This patch fixes a number of compile warnings when building a 32bit
U-Boot with CONFIG_PHYS_64BIT=y. In some places, it also fixes error
handling where the return value of dev_read_addr() etc. was checked for
NULL instead of FDT_ADDR_T_NONE.

<title>dma: ti: Update J21E PSIL endpoint information for MAIN CPSW0</title>

<id>066e860bc787d88c6d8c9beea8382ea1821297ea</id>
<content type='text'>
The PSIL endpoint data for J721E currently covers only the MCU domain
CPSW0 instance. Add the data for the MAIN domain CPSW0 as well to allow
the MAIN domain Ethernet ports to be usable on any platform using J721E
SoC.

Additionally, since J721E's PSIL endpoint data is applicable to J7200
SoC as well, the MAIN CPSW0 instance on J7200 will also be usable now.

Setting RX flow error handling will stall the channel until descriptors
are available to move RX data. Setting this bit causes issues when
tearing down ethernet DMA channel at the end of TFTP transfer as
unrelated network packets can cause teardown to stall indefinitely waiting
for driver to queue add more desc leading to channel hang with error
logs:
udma_stop_dev2mem TIMEOUT !
udma_stop_dev2mem: peer not stopped TIMEOUT !
udma_stop_dev2mem TIMEOUT !

Fix this by clearing rx_error_handling similar to how its done for UDMA
as part of udma_alloc_rchan_sci_req()

This fixes occasional TFTP Failures seen when downloading multiple files
one after the other on AM64/AM62 SoCs.

The way all of the memory init code here works is that we pass
0xDEADBEEF around for the initial value (as it's a well known 'poison'
value and so easily recognized in debuggers, etc). The only point of
this CONFIG symbol was to pass in a different value for that purpose.
Drop this symbol and cleanup the code slightly.

uclass_first_device/uclass_next_device return value will be removed,
don't use it.

With the current implementation dev is equivalent to !ret. It is
redundant to check both, ret check can be replaced with dev check, and
ret check inside the iteration is dead code.

DMA operations should function on DMA addresses, not virtual addresses.
Although these are usually the same in U-Boot, it is more correct

We should clean the caches before any DMA operation and clean+invalidate
after. This matches what the DMA framework does for us already but adds
it to the two functions here in this driver that don't yet go through the
new DMA framework.
