In U-Boot, LMB and EFI are two primary modules who provide memory
allocation and reservation API's. Both these modules operate with the
same regions of memory for allocations. Use the LMB memory map update
event to notify other interested listeners about a change in it's
memory map. This can then be used by the other module to keep track of
available and used memory.
There is no need to send these notifications when the LMB module is
being unit-tested. Add a flag to the lmb structure to indicate if the
memory map is being used for tests, and suppress sending any
notifications when running these unit tests.

This patch follows the upstream linux commit:
5273cc6df984("mtd: spi-nor: core: Call spi_nor_post_sfdp_fixups() only

spi_nor_post_sfdp_fixups() was called regardless of if
spi_nor_parse_sfdp() had been called or not. late_init() should be
instead used to initialize the parameters that are not defined in SFDP.
Ideally spi_nor_post_sfdp_fixups() is called only after successful parse
of SFDP. However, in case SFDP support is disabled by .config, that can
break current functionality. Therefore, we would call it after
spi_nor_parse_sfdp() regardless of its return value.

default_init() is wrong, it contributes to the maze of initializing
flash parameters. We'd like to get rid of it because the flash
parameters that it initializes are not really used at SFDP parsing time,
thus they can be initialized later.
Ideally we want SFDP to initialize all the flash parameters. If (when)
SFDP tables are wrong, we fix them with the post_sfdp/bfpt hooks, to
emphasize that SFDP is indeed wrong. When there are parameters that are
not covered by SFDP, we initialize them in late_init() - these
parameters have nothing to do with SFDP and they are not needed earlier.
With this we'll have a clearer view of who initializes what.
There are six default_init() hooks implemented just for initializing
octal_dtr_enable() and/or setup() hooks that called later on.
Just moving those to late_init() does not change functionality.

Some flashes like the Infineon SEMPER NOR flash family use ECC. Under
this ECC scheme, multi-pass writes to an ECC block is not allowed.
In other words, once data is programmed to an ECC block, it can't be
programmed again without erasing it first.
Upper layers like file systems need to be given this information so they
do not cause error conditions on the flash by attempting multi-pass
programming. This can be done by setting 'writesize' in 'struct
mtd_info'.
Set the default to 1 but allow flashes to modify it in fixup hooks. If
more flashes show up with this constraint in the future it might be
worth it to add it to 'struct flash_info', but for now increasing its
size is not worth it.

For NOR flashes EC and VID are zeroed out before an erase is issued to
make sure UBI does not mistakenly treat the PEB as used and associate it
with an LEB.
But on some flashes, like the Infineon Semper NOR flash family,
multi-pass page programming is not allowed on the default ECC scheme.
This means zeroing out these magic numbers will result in the flash
throwing a page programming error.
Do not zero out EC and VID for such flashes. A writesize > 1 is an
indication of an ECC-ed flash.

Integrate MbedTLS v3.6 LTS (currently v3.6.0) with U-Boot.
Motivations:
------------
1. MbedTLS is well maintained with LTS versions.
2. LWIP is integrated with MbedTLS and easily to enable HTTPS.
3. MbedTLS recently switched license back to GPLv2.
Prerequisite:
-------------
This patch series requires mbedtls git repo to be added as a
subtree to the main U-Boot repo via:
$ git subtree add --prefix lib/mbedtls/external/mbedtls \
https://github.com/Mbed-TLS/mbedtls.git \
v3.6.0 --squash
Moreover, due to the Windows-style files from mbedtls git repo,
we need to convert the CRLF endings to LF and do a commit manually:
$ git add --renormalize .
$ git commit
New Kconfig options:
--------------------
`MBEDTLS_LIB` is for MbedTLS general switch.
`MBEDTLS_LIB_CRYPTO` is for replacing original digest and crypto libs with
MbedTLS.
`MBEDTLS_LIB_CRYPTO_ALT` is for using original U-Boot crypto libs as
MbedTLS crypto alternatives.
`MBEDTLS_LIB_X509` is for replacing original X509, PKCS7, MSCode, ASN1,
and Pubkey parser with MbedTLS.
By default `MBEDTLS_LIB_CRYPTO_ALT` and `MBEDTLS_LIB_X509` are selected
when `MBEDTLS_LIB` is enabled.
`LEGACY_CRYPTO` is introduced as a main switch for legacy crypto library.
`LEGACY_CRYPTO_BASIC` is for the basic crypto functionalities and
`LEGACY_CRYPTO_CERT` is for the certificate related functionalities.
For each of the algorithm, a pair of `<alg>_LEGACY` and `<alg>_MBEDTLS`
Kconfig options are introduced. Meanwhile, `SPL_` Kconfig options are
introduced.
In this patch set, MBEDTLS_LIB, MBEDTLS_LIB_CRYPTO and MBEDTLS_LIB_X509
are by default enabled in qemu_arm64_defconfig and sandbox_defconfig
for testing purpose.
Patches for external MbedTLS project:
-------------------------------------
Since U-Boot uses Microsoft Authentication Code to verify PE/COFFs
executables which is not supported by MbedTLS at the moment,
addtional patches for MbedTLS are created to adapt with the EFI loader:
1. Decoding of Microsoft Authentication Code.
2. Decoding of PKCS#9 Authenticate Attributes.
3. Extending MbedTLS PKCS#7 lib to support multiple signer's certificates.
4. MbedTLS native test suites for PKCS#7 signer's info.
All above 4 patches (tagged with `mbedtls/external`) are submitted to
MbedTLS project and being reviewed, eventually they should be part of
MbedTLS LTS release.
But before that, please merge them into U-Boot, otherwise the building
will be broken when MBEDTLS_LIB_X509 is enabled.
See below PR link for the reference:
https://github.com/Mbed-TLS/mbedtls/pull/9001
Miscellaneous:
--------------
Optimized MbedTLS library size by tailoring the config file
and disabling all unnecessary features for EFI loader.
From v2, original libs (rsa, asn1_decoder, rsa_helper, md5, sha1, sha256,
sha512) are completely replaced when MbedTLS is enabled.
From v3, the size-growth is slightly reduced by refactoring Hash functions.
From v6, smaller implementations for SHA256 and SHA512 are enabled and
target size reduce significantly.
Target(QEMU arm64) size-growth when enabling MbedTLS:
v1: 6.03%
v2: 4.66%
v3 - v5: 4.55%
v6: 2.90%
Tests done:
-----------
EFI Secure Boot test (EFI variables loading and verifying, EFI signed image
verifying and booting) via U-Boot console.
EFI Secure Boot and Capsule sandbox test passed.
Known issues:
-------------
None.
