dtoc: Fix up tests

2017-11-23T01:05:38Z

The tool has changed slightly since it was originally written. Update the tests to suit. Signed-off-by: Simon Glass

binman: Disable the no-unit_address_vs_reg warnings

2017-11-23T01:05:38Z

These warnings are not useful for binman tests. Disable them. Signed-off-by: Simon Glass

2017-09-15T11:27:48Z

Add a header that indicates that the files generated by dtoc should not be modified. Signed-off-by: Simon Glass Tested-by: Kever Yang

dtoc: Support properties containing multiple phandle values

2017-09-15T11:27:48Z

At present dtoc has a very simplistic view of phandles. It assumes that a property has only a single phandle with a single argument (i.e. two cells per property). This is not true in many cases. Enhance the implementation to scan all phandles in a property and to use the correct number of arguments (which can be 0, 1, 2 or more) when generating the C code. For the struct definitions, use a struct which can hold the maximum number of arguments used by the property. Signed-off-by: Simon Glass Tested-by: Kever Yang

dtoc: Put phandle args in an array

2017-09-15T11:27:48Z

We want to support more than one phandle argument. It makes sense to use an array for this rather than discrete struct members. Adjust the code to support this. Rename the member to 'arg' instead of 'id'. Signed-off-by: Simon Glass Tested-by: Kever Yang

dtoc: Put each phandle on a separate line

2017-09-15T11:27:47Z

When writing values from properties which contain phandles, dtoc currently writes 8 phandles per line. Change this to write one phandle per line. This helps reduce line length, since phandles are generally longer and may have arguments. Signed-off-by: Simon Glass Tested-by: Kever Yang

dtoc: Rename the phandle struct

2017-09-15T11:27:47Z

Rather than naming the phandle struct according to the number of cells it uses (e.g. struct phandle_2_cell) name it according to the number of arguments it has (e.g. struct phandle_1_arg). This is a more intuitive naming. Signed-off-by: Simon Glass Tested-by: Kever Yang

dtoc: Rename is_phandle() and adjust it to return more detail

2017-09-15T11:27:47Z

Update this function to return more detail about a property that contains phandles. This will allow (in a future commit) more accurate handling of these properties. Signed-off-by: Simon Glass Tested-by: Kever Yang

dtoc: Make is_phandle() a member function

2017-09-15T11:27:47Z

This function will need to have access to class members once we enhance it to support multiple phandle values. In preparation for that, move it into the class. Signed-off-by: Simon Glass Tested-by: Kever Yang

dtoc: Use the Fdt's class's phandle map

2017-09-15T11:27:47Z

Now that the Fdt class can map phandles to the associated nodes, use that instead of a separate implementation. Signed-off-by: Simon Glass Tested-by: Kever Yang
