However, the PCS registers were being written before the PCSSEL bit was set in the network configuration register, and it appears that in this state, PCS register writes are ignored. The result is that the intended change only took effect on the second network operation that was performed, since at that time PCSSEL is already enabled. Fix the order of register writes so that PCS registers are only written to after the PCS is enabled.

This patch fixes this by using r6 instead of r4 in the lowlevel_init function. Discovered and the fix was tested on a AT91SAM9261 based board.

However this feature is needed for binman's expanded nodes, since there may be another node in the same section. While libfdt adds new properties after existing properties, it adds new subnodes before existing subnodes. This means that we must reorder the nodes in the cached version, so that the ordering remains consistent. Update the sync implementation to sync existing subnodes first, then add new ones, then tidy up the ordering in the cached version. Update the test to cover this behaviour. Also improve the comment about property syncing while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>

This will expand to adding multiple subnodes in future patches. Put a node after the one we are adding to so we can check that things sync correctly.

This 'lazy' refresh doesn't really save much time, since refresh is a very fast operation, just a single walk of the tree. Also, having the refresh happen in the bowels of property access it makes it harder to figure out what is going on. Simplify the code by always doing a refresh before and after a sync. Set _cached_offsets to True immediately after this, in the Refresh() function, since this makes more sense than doing it in the caller. Signed-off-by: Simon Glass <sjg@chromium.org>

This is partly to avoid wasting time, since the entries within sections may change multiple times as binman works through its various stages. This works quite well since sections exist in a strict hierarchy, so they can be processed in a depth-first manner. However the 'collection' entry type does not have this luxury. If it contains a section within its 'content' list, then it must produce the section contents, if available. That section is typically a sibling node, i.e. not part oc the collection's hierarchy. Add a new 'required' argument to section.GetData() to support this. When required is True, any referenced sections are immediately built. If this is not possible (because one of the subentries does not have its data yet) then an error is produced. The test for this uses a 'collection' entry type, referencing a section as its first member. This forces a call to _BuildSectionData() with required set to False, at first, then True later, when the image is assembled. Signed-off-by: Simon Glass <sjg@chromium.org>

| | * | | malloc: Export malloc_simple_info()Simon Glass2021-03-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Export this function always so it can be used behind IS_ENABLED() instead of requiring an #ifdef. Signed-off-by: Simon Glass <sjg@chromium.org>
| | * | | cpu: Rename SPL_CPU_SUPPORT to SPL_CPUSimon Glass2021-03-2710-14/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The _SUPPORT suffix is from an earlier time and interferes with use of the CONFIG_IS_ENABLED() macro. Rename the option to drop the suffix. Tidy up the TODO that prompted this. Signed-off-by: Simon Glass <sjg@chromium.org>
| | * | | sf: Support querying write-protectSimon Glass2021-03-277-1/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This feature was dropped from U-Boot some time ago: f12f96cfaf5 (sf: Drop spl_flash_get_sw_write_prot") However, we do need a way to see if a flash device is write-protected, since if it is, it may not be possible to write to do (i.e. failing to write is expected). I am not sure of the correct layer to implement this, so this patch is a stab at it. If spi-flash makes sense then I will add to the 'sf' also. Re the points mentioned in the removal commit: 1) This kind of requirement can be achieved using existing flash operations and flash locking API calls instead of making a separate flash API. Which uclass is this? 2) Technically there is no real hardware user for this API to use in the source tree. I do want coral (at least) to support this. 3) Having a flash operations API for simple register read bits also make difficult to extend the flash operations. This new patch only mentions write-protect being on or off, rather than the actual mechanism. 4) Instead of touching generic code, it is possible to have this functionality inside spinor operations in the form of flash hooks or fixups for associated flash chips. That sounds to me like what drivers are for. But we still need some sort of API for it to be accessible. Signed-off-by: Simon Glass <sjg@chromium.org>
| | * | | bootstage: Warning if space is exhaustedSimon Glass2021-03-271-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present bootstage silently ignores new records if it runs out of space. It is sometimes obvious by looking at the report, but the IDs are not contiguous, so it is easy to miss. Aad a message so that action can be taken. Signed-off-by: Simon Glass <sjg@chromium.org>
| | * | | spl: Split out bootstage ID into a functionSimon Glass2021-03-271-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have two separate places that need to figure out the bootstage ID to use. Put this code in a function so that the logic is in one place. Signed-off-by: Simon Glass <sjg@chromium.org>
| | * | | binman: Show a message when changing subnodesSimon Glass2021-03-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change seems important enough to warrant a visible message. Change the log_debug() to log_info(). Signed-off-by: Simon Glass <sjg@chromium.org>
