binman: Support updating the device tree with calc'd info

2018-07-09T15:11:00Z

It is useful to write the position and size of each entry back to the device tree so that U-Boot can access this at runtime. Add a feature to support this, along with associated tests. Signed-off-by: Simon Glass

binman: Tidy up setting of entry contents

2018-07-09T15:11:00Z

At present the contents of an entry are set in subclasses simply by assigning to the data and content_size properties. Add some methods to do this, so that we have more control. In particular, add a method to set the contents without changing its size, so we can validate that case. Add a test case for trying to change the size when this is not allowed.

binman: Correct operation of ObtainContents()

2018-07-09T15:11:00Z

This method is supposed to return the contents of an entry. However at present there is no check that it actually does. Also some implementations do not return 'True' to indicate success, as required. Add a check for things working as expected, and correct the implementations. This requires some additional test cases to cover things which were missed originally. Add these at the same time. Signed-off-by: Simon Glass

binman: Make the operation of Entry__testing explicit

2018-07-09T15:11:00Z

This fake entry is used for testing. At present it only has one behaviour which is to return an invalid set of entry positions, to cause an error. The fake entry will need to be used for other things too. Allow the test .dts file to specify the behaviour of the fake entry, so we can control its behaviour easily. While we are here, drop the ReadContents() method, since this only applies to subclasses of Entry_blob, which Entry__testing is not. Signed-off-by: Simon Glass

binman: Add support for adding a name prefix to entries

2018-06-07T19:25:08Z

Sometimes we have several sections which repeat the same entries (e.g. for a read-only and read-write version of the same section). It is useful to be able to tell these entries apart by name. Add a new 'name-prefix' property for sections, which causes all entries within that section to have a given name prefix. Signed-off-by: Simon Glass

binman: Add support for sections

2018-06-07T19:25:08Z

It is useful to be able to split an image into multiple sections, each with its own size and position, for cases where a flash device has read-only and read-write portions. Add support for this. Signed-off-by: Simon Glass

binman: Allow unit addresses for binaries

2018-06-07T19:25:07Z

Allow the same binary to appear multiple times in an image by using the device-tree unit-address feature (u-boot@0, u-boot@1). Signed-off-by: Simon Glass

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

binman: Support accessing binman tables at run time

2017-12-13T02:53:45Z

Binman construct images consisting of multiple binary files. These files sometimes need to know (at run timme) where their peers are located. For example, SPL may want to know where U-Boot is located in the image, so that it can jump to U-Boot correctly on boot. In general the positions where the binaries end up after binman has finished packing them cannot be known at compile time. One reason for this is that binman does not know the size of the binaries until everything is compiled, linked and converted to binaries with objcopy. To make this work, we add a feature to binman which checks each binary for symbol names starting with '_binman'. These are then decoded to figure out which entry and property they refer to. Then binman writes the value of this symbol into the appropriate binary. With this, the symbol will have the correct value at run time. Macros are used to make this easier to use. As an example, this declares a symbol that will access the 'u-boot-spl' entry to find the 'pos' value (i.e. the position of SPL in the image): binman_sym_declare(unsigned long, u_boot_spl, pos); This converts to a symbol called '_binman_u_boot_spl_prop_pos' in any binary that includes it. Binman then updates the value in that binary, ensuring that it can be accessed at runtime with: ulong u_boot_pos = binman_sym(ulong, u_boot_spl, pos); This assigns the variable u_boot_pos to the position of SPL in the image.

binman: Adjust size of test SPL binary

2017-12-13T02:53:45Z

This is only 3 bytes long which is not enough to hold two symbol values, needed to test the binman symbols feature. Increase it to 15 bytes. Using very small regions is useful since we can easily compare them in tests and errors are fairly easy to diagnose. Signed-off-by: Simon Glass
