cfi_flash: use specific width types for cword

architecture indepented.

This patch also renames the members of the cword union to represent
their usage, i.e.:

    c  -> w8
    s  -> w16
    l  -> w32
    ll -> w64

Where "w" stands for "width" in bits.

I discovered this problem when enabling CFI flash on vexpress64.
cword.l was an unsigned long int, but it was intended to be 32 bits wide.
Unfortunately, it's 64-bits wide on a 64-bit system, meaning that a

Bernhard Nortmann [Fri, 21 Aug 2015 13:13:21 +0000 (15:13 +0200)]
allow LED initialization without STATUS_LED_BOOT

For current U-Boot to initialize status LEDs via status_led_init(), it
is required to have both CONFIG_STATUS_LED and STATUS_LED_BOOT defined.
This may be a particular concern with GPIO LEDs, where __led_init() is
required to correctly set up the GPIO (gpio_request and
gpio_direction_output). Without STATUS_LED_BOOT the initialization isn't
called, which could leave the user with a non-functional "led" command -
due to the fact that the LED routines in gpio_led.c use gpio_set_value()
just fine, but the GPIO never got set up properly in the first place.

I think having CONFIG_STATUS_LED is sufficient to justify a
corresponding call to status_led_init(), even with no STATUS_LED_BOOT
defined. To do so, common/board_r.c needs call that routine, so it now
is exposed via status_led.h.

add generic stubs for GPIO LEDs

For boards that support LEDs driven via GPIO (CONFIG_GPIO_LED),
it may be useful to have some generic stubs (wrapper functions)
for the "colored" LEDs.

This allows defining STATUS_LED_* values directly to GPIO numbers,
e.g.: #define STATUS_LED_GREEN 248 /* = PH24 */

To keep those optional, it's probably best to introduce an additional
configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that.
Placing the code in drivers/misc/gpio_led.c also ensures that it
automatically depends on CONFIG_GPIO_LED too.

fdt: fix fdtdec_get_pci_addr() for CONFIG_PHYS_64BIT

PCI addresses are always represented as 3 cells in DT. (one cell for bus
and device, and two cells for a 64-bit addres). This does not vary based
on either the physical address size of the CPU, nor any #address-cells
property in DT (or more precisely, #address-cells must be set to 3 in any
PCIe controller's node).

Fix fdtdec_get_pci_addr() to use conversion functions that operate on
(fixed) cell-sized data rather than (varying) physical-address-sized
data, so that the function works on 64-bit systems.

nios2: define _end in link script

Since commit 44c6e6591cb451ae606f8bde71dd5fb7b4002544
"rename _end to __bss_end__" , the _end was removed.
But we need it now for separated device tree control,
ie, CONFIG_OF_SEPARATE .

The _end is used by fdtdec_setup() to find the blob.
