blk: Invalidate block cache when switching hwpart
Some storage devices have multiple hw partitions and both address from
zero, for example eMMC.
However currently block cache invalidation only applies to block
write/erase.
This can cause a problem that data of current hw partition is cached
before switching to another hw partition. And the following read
operation of the latter hw partition will get wrong data when reading
from the addresses that have been cached previously.
To solve this problem, invalidate block cache after a successful

tools: mkenvimage: Always consider non-regular files
At the moment mkenvimage has two separate read paths: One to read from
a potential pipe, while dynamically increasing the buffer size, and a
second one using mmap(2), using the input file's size. This is
problematic for two reasons:
- The "pipe" path will be chosen if the input filename is missing or
"-". Any named, but non-regular file will use the other path, which
typically will cause mmap() to fail:
$ mkenvimage -s 256 -o out <(echo "foo=bar")
- There is no reason to have *two* ways of reading a file, since the
"pipe way" will always work, even for regular files.
Fix this (and simplify the code on the way) by always using the method
of dynamically resizing the buffer. The existing distinction between
the two cases will merely be used to use the open() syscall or not.

It is perfectly fine for the read(2) syscall to return with less than
the requested number of bytes read (short read, see the "RETURN VALUE"

(keyboard, network) or with complex pipes.
So far mkenvimage expects the exact number of requested bytes to be
read, assuming an end-of-file condition otherwise. This wrong behaviour
can be easily shown with:
$ (echo "foo=bar"; sleep 1; echo "bar=baz") | mkenvimage -s 256 -o out -
The second line will be missing from the output.

See doc/driver-model/MIGRATION.txt for more info.
====================================================
Change the defconfig to disable MMC until a driver is submitted.

board: ti: am654: Use EEPROM-based board detection
The TI AM654x EVM base board and the associated daughtercards have on-
board I2C-based EEPROMs containing board configuration data. Use the
board detection infrastructure introduced earlier to do the following:
1) Parse the AM654x EVM base board EEPROM and populate items like board
name and MAC addresses into the TI common EEPROM data structure
residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing the associated
presence signals via an I2C-based GPIO expander. Then, if such a
card is found, parse the data such as additional Ethernet MAC
addresses from its on-board EEPROM and populate into U-Boot
accordingly
3) Dynamically create an U-Boot ENV variable called overlay_files
containing a list of daugherboard-specific DTB overlays based on
daughercards found.
This patch adds support for the AM654x base board ("AM6-COMPROCEVM")
as well as for the IDK ("AM6-IDKAPPEVM"), OLDI LCD ("OLDI-LCD1EVM")
PCIe/USB3.0 ("SER-PCIEUSBEVM"), 2 Lane PCIe/USB2.0 ("SER-PCIE2LEVM"),
and general purpuse ("AM6-GPAPPEVM") daughtercards.

ti: common: am6: Add support for setting MAC addresses
The AM654x EVM based on the TI K3 family of SoCs has an updated board
detection EEPROM structure that contains a TLV record of dedicated MAC
addresses rather than a range of MAC addresses as it was used on earlier
platforms such as DRA7. Add a basic function that allows us setting up
Ethernet MAC addresses into the U-Boot environment based on the MAC
address record contained in the common TI EEPROM structure.

ti: common: am6: Add support for board description EEPROM
The AM654x EVM based on the TI K3 family of SoCs have an updated board

earlier platforms such as DRA7. Add basic support for parsing the new

to parse data from additional EEPROMs such as the ones that are used on

arm: K3: am654: Map common EEPROM data into SRAM scratch space
The board detection scheme employed on various TI EVMs makes use of
SRAM scratch space to share data read from an on-board EEPROM between
the different bootloading stages. Map the associated definition that's
used to locate this data into the SRAM scratch space we use on AM654x.
