The SCU API alreay has been converted to return Linux error code, using SCU error code is not correct here, although SC_ERR_NONE is value as 0. Signed-off-by:Peng Fan <peng.fan@nxp.com>

Using the PKI tree with SRKs as intermediate CA isn't necessary or even desirable in some situations (boot time, for example). Add the possibility to use the "fast authentication" method where the image and CSF are both signed using the SRK [1, p.63].

Simplify code and conform to the style guide used in the project by making the following changes: * Capitalize global constants * Use single quotes for multiline strings (except docstrings) * Fix line width to 79 cols * Use f-string instead of formatting a regular string or using a complicated concatenation * Move common suffix used in keys to a global variable "KEY_NAME" to reduce the likelihood of typos and making future changes easier Signed-off-by: -

When OSCCA is enabled, FSB fuse shadow (offset 0x8000) access is disabled for SOC. So update the driver to read fuse from ELE API. The ELE has supported to read all shadow fuses like FSB, reuse the table of FSB for the word index used by ELE API. Add ELE shadow fuse read and write to current ELE fuse driver. But when LC is OEM closed, the ELE read/write shadow fuse APIs are forbidden. Reading from any fuse will return error. This causes problem to u-boot which must read out some fuse no matter whatever LC. So we have to change back to read from FSB and ELE common fuse read API. For using ELE shadow read API for development purpose like checking the ELE shadow fuse write result, user can set env variable "enable_ele_shd" to y to switch it. Reviewed-by:

There is a bug when checking fuse word with redundancy fuse in FSB table. The redundancy fuses are combined into 4 words, so we can't directly use word index to do the check, otherwise the high 4 words will fail to match. And When calling ELE API, res parameter will pass to ELE API to get ELE response value for failure. So most of usage does not initialize this variable and print it after calling ELE API. However, when ELE API returns failure, we can't ensure this res is always set because there may be other failure like MU failure. Reviewed-by:

On iMX8ULP, the word index 1 is used to read OTP_UNIQ_ID with 4 words data responsed. However this special index does not apply others. So restrict the check to i.MX8ULP to avoid problem when reading from fuse word 1 for others, such as i.MX93. Also update header order Signed-off-by: -
When OS is doing ELE API call, before OS get the response, OS is force reseted, then it is possible that MU RR has data during initialization in SPL stage. So clear the RR registers, otherwise SPL ELE API call will work abnormal. Cc: Alice Guo <alice.guo@nxp.com> Cc: Marek Vasut <marex@denx.de> Signed-off-by: -
The MU parameter register can provide the TR and RR number. For i.MX95 which has 8 RR is different with i.MX93 and i.MX8ULP, so update the driver to read the PAR for exact TR and RR number. Also update compatible string for i.MX95 ELE MU. Cc: Alice Guo <alice.guo@nxp.com> Cc: Marek Vasut <marex@denx.de> Reviewed-by:

Simon Glass <sjg@chromium.org> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to...

Take account of the new XPL_ and PHASE_ instead of the old SPL_ and SPL_TPL_ Signed-off-by: -
Rename these to use the word PHASE instead. Signed-off-by: -
Use PHASE_ as the symbol to select a particular XPL build. This means that SPL_TPL_ is no-longer set. Update the comment in bootstage to refer to this symbol, instead of SPL_ Signed-off-by: -
Use XPL_ as the symbol to indicate an SPL build. This means that SPL_ is no-longer set. Signed-off-by: -
Now that SPL means SPL (only) and is not defined for other phases, update kconfig rules. This is done in one patch since otherwise many Binman tests fail. Signed-off-by: -

This should not be in the generic README file, so drop it. Signed-off-by: -
Update the various references to SPL in this document. Make sure to refer to 'phases' instead of 'stages', which is not a U-Boot term. Fix a few U-boot typos and try to improve grammar a little while we are here. Signed-off-by: -

This now appears in the code base, so add it to the list of ignored symbols in qconfig Signed-off-by: -
The new name 'xPL' is intended to indicate a build of any phase which is not U-Boot proper. Define it for all such phases. Note that we also define CONFIG_SPL_BUILD for all xPL builds. This preserves existing behaviour, but future patches will adjust that. Signed-off-by: -
