- * AT91SAM9XE devices with the following geometry:
- *
- * AT91SAM9XE128: 1 plane of 8 regions of 32 pages (total 256 pages)
- * AT91SAM9XE256: 1 plane of 16 regions of 32 pages (total 512 pages)
- * AT91SAM9XE512: 1 plane of 32 regions of 32 pages (total 1024 pages)
- * (the exact geometry is read from the flash at runtime, so any
- * future devices should already be covered)
- *
- * Regions can be write/erase protected.
- * Whole (!) pages can be individually written with erase on the fly.
- * Writing partial pages will corrupt the rest of the page.
- *
- * The flash is presented to u-boot with each region being a sector,
- * having the following effects:
- * Each sector can be hardware protected (protect on/off).
- * Each page in a sector can be rewritten anytime.
- * Since pages are erased when written, the "erase" does nothing.
- * The first "CONFIG_EFLASH_PROTSECTORS" cannot be unprotected
- * by u-Boot commands.
- *
- * Note: Redundant environment will not work in this flash since
- * it does use partial page writes. Make sure the environment spans
- * whole pages!
- */
-
-/*
- * optional TODOs (nice to have features):
- *
- * make the driver coexist with other NOR flash drivers
- * (use an index into flash_info[], requires work
- * in those other drivers, too)
- * Make the erase command fill the sectors with 0xff
- * (if the flashes grow larger in the future and
- * someone puts a jffs2 into them)
- * do a read-modify-write for partially programmed pages

+ *
+ * To use it you should:
+ * - Make sure your UART supports this interface
+ * - Enable CONFIG_DEBUG_UART
+ * - Enable the CONFIG for your UART to tell it to provide this interface
+ * (e.g. CONFIG_DEBUG_UART_NS16550)
+ * - Define the required settings as needed (see below)
+ * - Call debug_uart_init() before use
+ * - Call printch() to output a character
+ *
+ * Depending on your platform it may be possible to use this UART before a
+ * stack is available.
+ *
+ * If your UART does not support this interface you can probably add support
+ * quite easily. Remember that you cannot use driver model and it is preferred
+ * to use no stack.
+ *
+ * You must not use this UART once driver model is working and the serial
+ * drivers are up and running (done in serial_init()). Otherwise the drivers
+ * may conflict and you will get strange output.
+ *
+ *
+ * To enable the debug UART in your serial driver:
+ *
+ * - #include <debug_uart.h>
+ * - Define debug_uart_init(), trying to avoid using the stack
+ * - Define _debug_uart_putc() as static inline (avoiding stack usage)
+ * - Immediately afterwards, add DEBUG_UART_FUNCS to define the rest of the
