Simon Glass 295d3942b8 Add board_pre_console_putc to deal with early console output 
This patch adds support for console output before the console is inited.
The main purpose of this is to deal with a very early panic() which would
otherwise cause a silent hang.

A new board_pre_console_putc() function is added to the board API. If
provided by the board it will be called in the event of console output
before the console is ready. This function should turn on all UARTs and
spray the character out if it possibly can.

The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option.

/*
* The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
* stack that meets the minimum architecture alignment requirements for DMA.
* Such a buffer is useful for DMA operations where flushing and invalidating
* the cache before and after a read and/or write operation is required for
* correct operations.
*
* When called the macro creates an array on the stack that is sized such
* that:
*
* 1) The beginning of the array can be advanced enough to be aligned.
*
* 2) The size of the aligned portion of the array is a multiple of the minimum
* architecture alignment required for DMA.
*
* 3) The aligned portion contains enough space for the original number of
* elements requested.
*
* The macro then creates a pointer to the aligned portion of this array and
* assigns to the pointer the address of the first element in the aligned
* portion of the array.
*
* Calling the macro as:
*
* ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
*
* Will result in something similar to saying:
*
* uint32_t buffer[1024];
*
* The following differences exist:
*
* 1) The resulting buffer is guaranteed to be aligned to the value of
* ARCH_DMA_MINALIGN.
*
* 2) The buffer variable created by the macro is a pointer to the specified
* type, and NOT an array of the specified type. This can be very important
* if you want the address of the buffer, which you probably do, to pass it
* to the DMA hardware. The value of &buffer is different in the two cases.
* In the macro case it will be the address of the pointer, not the address
* of the space reserved for the buffer. However, in the second case it
* would be the address of the buffer. So if you are replacing hard coded
* stack buffers with this macro you need to make sure you remove the & from
* the locations where you are taking the address of the buffer.
*
* Note that the size parameter is the number of array elements to allocate,
* not the number of bytes.
*
* This macro can not be used outside of function scope, or for the creation
* of a function scoped static buffer. It can not be used to create a cache
* line aligned global buffer.
