Subsystems such as USB expect dma_map_single() and dma_unmap_single() to
do dcache flush/invalidate operations as required. For example, see
see drivers/usb/gadget/udc/udc-core.c::usb_gadget_map_request().
Currently drivers do this locally, (see drivers/usb/dwc3/ep0.c,
drivers/mtd/nand/raw/denali.c etc..)
Update arch specific dma_map_single() and dma_unmap_single() APIs to do
cache flush/invalidate operations, so that drivers need not implement
them locally.

The ST-Ericsson U8500 SoC has been used in mass-production for
some Android smartphones released around 2012.
In particular, Samsung has released more than 5 different
smartphones based on U8500, e.g.
- Samsung Galaxy S III mini (GT-I8190) "golden"
- Samsung Galaxy S Advance (GT-I9070) "janice"
- Samsung Galaxy Xcover 2 (GT-S7710) "skomer"
and a few others.
Mainline Linux has great support for the Ux500 SoC, so these
smartphones can also run Linux mainline quite well.
Unfortunately, the original Samsung bootloader used on these devices
has limitations that prevent booting Linux mainline directly.
It keeps the L2 cache enabled, which causes Linux to crash very early,
shortly after decompressing the kernel.
Using U-Boot allows to circumvent these limitations. We can let the
Samsung bootloader chain-load U-Boot and U-Boot locks the L2 cache
before booting into Linux. U-Boot has several other advantages
- it supports device-trees directly and we are no longer limited to
flashing Android boot images through Samsung's proprietary download
mode.
The Samsung "stemmy" board covers all Samsung devices based on U8500.
Add minimal support for "stemmy". For now only UART is supported but
this will be extended later.

The NovaThor U8500 SoC was released by ST-Ericsson in 2011.
It was used for some development boards like the CALAO Systems
Snowball SBC, but mass production was primarily for Android
smartphones like the Samsung Galaxy S III mini.
Previous support for U8500 was removed in
commit 68282f55b8 ("arm: Remove unused ST-Ericsson u8500 arch")
since none of the boards were converted to generic boards
before the deadline.
The new code does not have much in common with the previous code.
I have completely rewritten everything, embracing the Driver Model
and device trees wherever possible.
The U8500 support is a bit more minimal for now - my primary
use case is to use U-Boot as alternative bootloader for some of the
U8500 Samsung smartphones. At the moment U-Boot is chain-loaded from
the original Samsung bootloader. A side effect of this is that we
can (temporarily) get away without implementing some functionality
- e.g. all clocks are already enabled by the original bootloader.
More functionality will be added in future patches.

ROM configures certain firewalls based on its usage, which includes
the one in front of boot peripherals. In specific case of boot
peripherals, ROM does not open up the full address space corresponding
to the peripherals. Like in OSPI, ROM only configures the firewall region
for 32 bit address space and mark 64bit address space flash regions
as in-accessible.
When security-cfg is initialized by sysfw, all the non-configured
firewalls are kept in bypass state using a global setting. Since ROM
configured firewalls for certain peripherals, these will not be touched.
So when bootloader touches any of the address space that ROM marked as
in-accessible, system raises a firewall exception causing boot hang.
It would have been ideal if sysfw cleans up the ROM configured boot
peripheral firewalls. Given the memory overhead to store this
information provided by ROM and the boot time increase in re configuring
the firewalls, it is concluded to clean this up in bootloaders.
So disable all the firewalls that ROM doesn't open up the full address
space.

On K3 systems U-Boot runs on both an R5 and a large ARM cores (usually
A53 or A72). The large ARMs are coherent with the DMA controllers and
the SYSFW that perform authentication. And previously the R5 core did
not enable caches. Now that R5 does enable caching we need to be sure
to clean out any of the image that may still only be in cache before we
read it using external DMA for authentication.
Although not expected to happen, it may be possible that the data was
read back into cache after the flush but before the external operation,
in this case we must invalidate our stale local cached version.

The TI J721E EVM system on module (SOM), the common processor board, and
the associated daughtercards have on-board I2C-based EEPROMs containing
board config data. Use the board detection infrastructure to do the
following:
1) Parse the J721E SOM EEPROM and populate items like board name, board
HW and SW revision as well as board serial number into the TI common
EEPROM data structure residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing associated I2C
addresses used for on-board EEPROMs containing daughter card-specific
data. If such a card is found, parse the EEPROM data such as for
additional Ethernet MAC addresses and populate those into U-Boot
accordingly
3) Dynamically apply daughter card DTB overlays to the U-Boot (proper)
DTB during SPL execution
4) Dynamically create an U-Boot ENV variable called name_overlays
during U-Boot execution containing a list of daugherboard-specific
DTB overlays based on daughercards found to be used during Kernel
boot.
