cab1306a09 configs: j72*_evm: Define the buffer sizes for dfu
On J721e R5 SPL, dfu buffer for loading sysfw.itb image gets allocated
before DRAM gets initialized. So, the buffer gets allocated in MCU L3
RAM. The current buffer size to be allocated is 256KB  and the available
total heap memory is 0x70000 (448KB). This leads to NOMEM errors during
allocation.

In other cases when constraints such as above are not present fix the size
of buffers to the sector size in OSPI for proper functioning.

Also, if CONFIG_SYS_DFU_DATA_BUF_SIZE is defined and
CONFIG_SYS_DFU_MAX_FILE_SIZE is not defined then the max file size for dfu
transfer is defined as CONFIG_SYS_DFU_DATA_BUF_SIZE.

Fix these by setting appropriate buffer sizes in their respective defconfig
files and defining the max file size as 8 MB which is the default dfu
buffer size.

7d67334dfe tools: k3_fit_atf: Fix DM binary FIT load addresses
The DM binary runs on the MCU R5F Core0 after R5 SPL on J721E and J7200
SoCs. The binary is built alongside the TFA, OPTEE and A72 SPL binaries
and included in the tispl.bin FIT image. The R5 SPL loads the DM binary
at 0xA0000000 address, based on the value used in the FIT image build
script. The DM binary though is an ELF image and not a regular binary
file, and so is processed further to load the actual program segments
using the U-Boot's standard ELF loader library.

The DM binary does leverage a certain portion of DDR for its program
segments, and typically reserves 16 MB of DDR at 0xA0000000 with the
1st MB used for IPC between Linux and the remote processor, and
remaining memory for firmware segments. This can cause an incomplete
loading of the program segments if the DM binary is larger than 1 MB,
due to overlap of the initial loaded binary and the actual program
segments.

Fix this by using the address 0x89000000, which matches the current
"addr_mcur5f0_0load" env variable used by R5 SPL before the DM firmware
inclusion into the tispl.bin.

5df1ee4594 arm: mvebu : sata_mv should probe all ports
While a board could have multiple SATA ports, some of the ports might
not have a disk attached to them. So while probing for disks,
sata_mv_probe() should continue probing all ports, and skip one with
no disk attached.

Tests with:

- Seagate Goflex Net (Marvell Kirkwood 88F6281) out-of-tree u-boot.
- Zyxel NSA325 (Marvell Kirkwood 88F6282 out-of-tree u-boot.

Observation:

If a board has 2 or more SATA ports, and there is only one disk
attached to one of the ports, sata_mv_probe() does not return
a successful probe status. And if only one disk is attached to the
2nd port (i.e. port 1), it is not probed at all.

Patch Description:

Let sata_mv_probe() continues probing all ports, even if there
is error in probing a given port, and then return a successful
status if there is at least one port was probed successfully.

d9ac6e28af arm: a37xx: pci: Implement re-issuing config requests on CRS response
According to PCIe base specification, if CRS Software Visibility is not

Request.

Normally this part of Root Complex is implemented in hardware but aardvark
is somehow special and does not implement it in hardware and expect that
handling of config requests are fully implemented in software.

This re-issuing functionality is required also because U-Boot does not
support CRS Software Visibility feature and therefore expects that Root
Complex re-issues requests as is specified in PCIe base specification.

Retry / re-issue config request up to the PIO_MAX_RETRIES, to prevent
infinite loop. After retry count exceed PIO_MAX_RETRIES, returns failure.

This does mean that we now have to 'select HASH' to make sure we get

even basic FITs will have to deal with "hash" nodes.

My only concern is that the 'select SPL_HASH' might cause some

fe54aeaa4a common: Move MD5 hash to hash_algo[] array.
MD5 is being called directly in some places, but it is not available
via hash_lookup_algo("md5"). This is inconsistent with other hasing
routines. To resolve this, add an "md5" entry to hash_algos[].

The #ifdef clause looks funnier than those for other entries. This is
because both MD5 and SPL_MD5 configs exist, whereas the other hashes
do not have "SPL_" entries. The long term plan is to get rid of the
ifdefs, so those should not be expected to survive much longer.

The md5 entry does not have .hash_init/update/finish members. That's
okay because hash_progressive_lookup_algo() will catch that, and
return -EPROTONOSUPPORT, while hash_lookup_algo() will return the
correct pointer.

e60e449931 lib: Drop SHA512_ALGO in lieu of SHA512
SHA512_ALGO was used as a "either SHA512 or SHA384", although the
implementations of these two algorithms share a majority of code.

From a Kconfig interface perspective, it makes sense to present two
distinct options. This requires #ifdefing out the SHA512
implementation from sha512.c. The latter doesn't make any sense.

It's reasonable to say in Kconfig that SHA384 depends on SHA512, and
seems to be the more polite way to handle the selection.

Thus, automatically select SHA512 when SHA384 is enabled.

The extra "_FIT_" variants are neither used, nor needed. Remove them.
One defconfig disables FIT_SHA256, which is now changed to 'SHA256'.

CMD_MVEBU_BUBT needs to select select SHA256 to avoid undefined
references to "sha256_*()". bubt.c needs sha256, so this selection is
correct. It is not clear why this problem did not manifest before.

Note that SHA selection in SPL is broken for this exact reason. There
is no corresponding SPL_SHAxxx. Fixing this is is beyond the scope of
this change.

Also note that we make CONFIG_FIT now imply SHA256, to make up for
FIT_SHA256 previously being a default y option.

213ed175b0 riscv: lib: implement enable_caches for sifive cache
The enable_caches is a generic hook for architecture-implemented, we
define this function to enable composable cache of sifive platforms.

In sifive_cache, it invokes the generic cache_enable interface of cache
uclass to execute the relative implementation in SiFive ccache driver.

43a2183928 cache: add sifive composable cache driver
This driver is currently responsible for enabling all ccache ways.
Composable cache could be configure as RAM or cache, we will use it as
RAM at the beginning to put the u-boot SPL there. In u-boot proper
phrase, we will use the composable cache as cache, and try to enable the
cache ways.

f6431e8fb3 riscv: show code leading to exception
To make analyzing exceptions easier output the code that leads to it.
We already do the same on the ARM platform.

Here is an example:

    => exception ebreak
    Unhandled exception: Breakpoint
    EPC: 000000008ff5d50e RA: 000000008ff5d62c TVAL: 0000000000000000
    EPC: 000000008020b50e RA: 000000008020b62c reloc adjusted

    Code: 2785 0693 07a0 dce3 fef6 47a5 d563 00e7 (9002)

To disassemble the code we can use the decodecode script:

    $ echo 'Code: 2785 0693 07a0 dce3 fef6 47a5 d563 00e7 (9002)' | \
      CROSS_COMPILE=riscv64-linux-gnu- scripts/decodecode

    Code: 2785 0693 07a0 dce3 fef6 47a5 d563 00e7 (9002)
    All code
    ========
       0:   2785                    addiw   a5,a5,1
       2:   07a00693                li      a3,122
       6:   fef6dce3                bge     a3,a5,0xfffffffffffffffe
       a:   47a5                    li      a5,9
       c:   00e7d563                bge     a5,a4,0x16
      10:*  9002                    ebreak         <-- trapping instruction
            ...

    Code starting with the faulting instruction
    ===========================================
       0:   9002                    ebreak
            ...

As it is not always clear if the first 16 bits are at the start or in the
middle of a 32bit instruction it may become necessary to strip the first
u16 from the output before calling decodecode to get the correct
disassembled code.
