To support the use of 'expanded' entries, binman needs to be told whether SPL and TPL have a devicetree and whether they need BSS padding. Add these to the Makefile. Signed-off-by: NSimon Glass <sjg@chromium.org>

When creating an entry, check for an expanded version of that entry, then use it instead. This allows, for example use of: u-boot { }; instead of having to write out in full: u-boot { type = "section"; u-boot-nodtb { }; u-boot-dtb { }; }; Add an implementaion of this and associated documentation.

Add support for this feature in the control, image and section modules, so that expanded entries will be selected by default. So far there are no expanded entry types, so this is a nop. Signed-off-by: NSimon Glass <sjg@chromium.org>

Add a new command-line option to disable expanded entries. This is needed for most tests, since it is much easier to 'factor out' this function into a separate test and keep the existing packing tests simple. Add the option and select it by default from tests. Signed-off-by: NSimon Glass <sjg@chromium.org>

As the first step in supporting expanded entries, add a way for binman to automatically select an 'expanded' version of an entry type, if requested. This is controlled by a class method. Signed-off-by: NSimon Glass <sjg@chromium.org>

At present, before any entry expansion is done (such as a 'files' entry expanding out to individual entries for each file it contains), we check the binman definition (i.e. '/binman' node) to find out what devicetree files are used in the images. This is a pain, since the definition may change during expansion. For example if there is no u-boot-spl-dtb entry in the definition at the start, we assume that the SPL devicetree is not used. But if an entry later expands to include this, then we don't notice. In fact the flexibility provided by the current approach of checking the definition is not really useful. We know that we can have SPL and TPL devicetrees. We know the pathname to each, so we can simply check if the files are present. If they are present, we can prepare them and update them regardless of whether they are actually used. If they are not present, we cannot prepare/update them anyway, i.e. an error will be generated. Simplify state.Prepare() so it uses a hard-coded list of devicetree files. Note that state.PrepareFromLoadedData() is left untouched, since in that case we have a complete definition from the loaded file, but cannot of course rely on the devicetree files that created it still being present. So in that case we still check the image defitions. Signed-off-by: NSimon Glass <sjg@chromium.org>

At present we store an entry as the third field in output_fdt_info[]. This is only used to get the type of the entry. Of course multiple entries may have this same type. Also the entry type is the key to this dict, so we can use that instead. Drop the field and update GetUpdateNodes() to suit. Improve the comment for output_fdt_info a little while here.

At present we always use the main devicetree for SPL/TPL as well when setting up the state. But this it not needed if there is a real devicetree for SPL or TPL. In fact it confuses things since we cannot distinguish between one being provided and using the fake one. Update the code to create the fakes only when requested. Put the mapping in a constant so we can use it elsewhere. Rename 'other_fname' to 'fname' while we are here since there is nothing 'other' about it. Signed-off-by: NSimon Glass <sjg@chromium.org>

This entry holds the padding between the end of of TPL binary and the end of BSS. This region must be left empty so that the devicetree can be appended correctly and remain accessible without interfering with BSS. Signed-off-by: NSimon Glass <sjg@chromium.org>

Several entries currently use an underscore in the entry-type name, but in fact a hyphen is used. Update the docs to fix this as it might be confusing. Also simplify the 'filename' comment and fix the 'operation' typo. Signed-off-by: NSimon Glass <sjg@chromium.org>

These devices are not actually built in TPL but are currently active in the TPL devicetree. For of-platdata-inst this means that we will try to generate devices for them, which fails.

With TPL we don't need full PCI support and it adds to code size. Instead, a simple_bus driver is good enough to be able to read and write the PCI config and do a little basic setup. So at present there are two drivers in U-Boot called pci_x86. One is in UCLASS_PCI, used in SPL and U-Boot proper. The other is in UCLASS_SIMPLE_BUS and used only in TPL. Add a tag to tell dtoc about this, so it knows which one to use when generating the devices and uclasses. Signed-off-by: NSimon Glass <sjg@chromium.org> Signed-off-by: NSimon Glass <sjg@chromium.org>

This doc has a few pieces that are out-of-date. Fix these. Also we have started to use 'devicetree' instead of 'device tree' or 'device-tree' since it is easier to see as a single term, so replace all ocurrences accordingly. Also move the caveats to the end, since this is a fairly solid part of U-Boot now. Signed-off-by: NSimon Glass <sjg@chromium.org> Signed-off-by: NSimon Glass <sjg@chromium.org>

At present the device priv/data data allocated by dtoc is stored in the data section along with other variables.

When of-platdata-inst is active, use the flags in the new udevice_rt table, dropping them from the main struct udevice. This ensures that the latter is not updated at runtime. Signed-off-by: NSimon Glass <sjg@chromium.org> Signed-off-by: NSimon Glass <sjg@chromium.org>

At present when driver model needs to change a device it simply updates the struct udevice structure. But with of-platdata-inst most of the fields are not modified at runtime. In fact, typically only the flags need to change. For systems running SPL from read-only memory it is convenient to separate out the runtime information, so that the devices don't need to be copied before being used. Create a new udevice_rt table, similar to the existing driver_rt. For now it just holds the flags, although they are not used in this patch. Add a new Kconfig for the driver_rt data, since this is not needed when of-platdata-inst is used. Signed-off-by: NSimon Glass <sjg@chromium.org> Signed-off-by: NSimon Glass <sjg@chromium.org>

Some systems (e.g. x86 APL) run SPL from read-only memory. The device instances created by dtoc are therefore not writeable. To make things work we would need to copy the devices to read/write memory. To avoid this, add an option to use a separate runtime struct for devices, just as is done for drivers. This can be used to hold information that changes at runtime, avoiding the need for a copy. Also add a Kconfig option for read-only SPL, which selects this feature.
