At present the FDTs are keyed by their default filename (not their actual filename). It seems easier to key by the entry type, since this is always the same for each FDT type. To do this, add a new Entry method called GetFdtEtype(). This is necessary since some entry types contain a device tree which are not the simple three entry types 'u-boot-dtb', 'u-boot-spl' or 'u-boot-tpl'. The code already returns a dict for GetFdt(). Update the value of that dict to include the filename so that existing code can work. Signed-off-by: Simon Glass <sjg@chromium.org>
