2016-08-10elog: Ensure eventlog will always get initialized when configured inJulius Werner
Commit 0d9cd92e (chromeos: Clean up elog handling) removed the individual elog_init() calls from mainboards that did them and automated adding certain events through the boot state machine. Unfortunately, the new code would sometimes not log any specific event at all, and thereby also never call elog_init() (through elog_add_event()) which adds the "System boot" event. We can assume that any board that configures the eventlog at all actually wants to use it, so let's just add another call to elog_init() to the boot state machine so we can ensure it gets called at least once.

The elog code calculates flash offsets and their equivalent addresses in the memory address space. However, it assumes the detected flash size is entirely mapped into the address space. This can lead to incorrect calculations. Add code to allow ROM_SIZE to be less than detected flash size. The underlying assumption is that the first ROM_SIZE bytes are programmed into the larger device.

2013-12-02elog: Get rid of the descriptor type and some unnecessary wrappersGabe Black
There was always exactly one elog descriptor declared and initialized, but its contents were being accessed through a pointer that was passed back and forth between functions instead of being accessed directly. This made the code more verbose than it needed to be and harder to follow. To address this the descriptor type was eliminated, its contents were turned into individual global variables, and various functions were adjusted to no longer take the descriptor as an argument. Similarly, the code was more verbose and complicated than it needed to be because of several wrapper functions which wrapped a single line of code which called an underlying function with particular arguments and were only used once. This makes it harder to tell what the code is doing because the call to the real function you may already be familiar with is obscured behind a new function you've never seen before. It also adds one more text to the file as a whole while providing at best a marginal benefit. Those functions were removed and their callers now call their contents directly.
