Eric Nelson 5ca05c8b03 cfb_console: align fields in gzipped .bmp files 
.bmp files contain 32-bit integers aligned at offsets of +2, +6,
et cetera within the bmp_header structure (see include/bmp_layout.h).

Support for gzip-compressed .bmp files is present in the cfb_console
display subsystem by uncompressing them prior to use.

This patch forces the in-memory header to be aligned properly
for these compressed images by extracting them to a 2-byte
offset in the memory returned by malloc. Since malloc will always
return a 4-byte aligned value, this forces the .bmp header
fields to be naturally aligned on 4-byte addresses.

Refer to these files for more details:

/*
* cfb_console.c
*
* Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
*
* At the moment only the 8x16 font is tested and the font fore- and
* background color is limited to black/white/gray colors. The Linux
* logo can be placed in the upper left corner and additional board
* information strings (that normally goes to serial port) can be drawn.
*
* The console driver can use the standard PC keyboard interface (i8042)
* for character input. Character output goes to a memory mapped video
* framebuffer with little or big-endian organisation.
* With environment setting 'console=serial' the console i/o can be
* forced to serial port.
*
* The driver uses graphic specific defines/parameters/functions:
*
* (for SMI LynxE graphic chip)
*
* CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810
* VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian
* VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill
* VIDEO_HW_BITBLT - graphic driver supports hardware bit blt
*
* Console Parameters are set by graphic drivers global struct:
*
* VIDEO_VISIBLE_COLS - x resolution
* VIDEO_VISIBLE_ROWS - y resolution
* VIDEO_PIXEL_SIZE - storage size in byte per pixel
* VIDEO_DATA_FORMAT - graphical data format GDF
* VIDEO_FB_ADRS - start of video memory
*
* CONFIG_I8042_KBD - AT Keyboard driver for i8042
* VIDEO_KBD_INIT_FCT - init function for keyboard
* VIDEO_TSTC_FCT - keyboard_tstc function
* VIDEO_GETC_FCT - keyboard_getc function
*
* CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with
* delay loop in VIDEO_TSTC_FCT (i8042)
*
* CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
* CONFIG_CONSOLE_TIME - display time/date in upper right
* corner, needs CONFIG_CMD_DATE and
* CONFIG_CONSOLE_CURSOR
* CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner.
* Use CONFIG_SPLASH_SCREEN_ALIGN with
* environment variable "splashpos" to place
* the logo on other position. In this case
* no CONSOLE_EXTRA_INFO is possible.
* CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
* CONFIG_CONSOLE_EXTRA_INFO - display additional board information
* strings that normaly goes to serial
* port. This define requires a board
* specific function:
* video_drawstring (VIDEO_INFO_X,
* VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
* info);
* that fills a info buffer at i=row.
* s.a: board/eltec/bab7xx.
* CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be
* initialized as an output only device.
* The Keyboard driver will not be
* set-up. This may be used, if you have
* no or more than one Keyboard devices
* (USB Keyboard, AT Keyboard).
*
* CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
* character. No blinking is provided.
* Uses the macros CURSOR_SET and
* CURSOR_OFF.
*
* CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability
* of the graphic chip. Uses the macro
* CURSOR_SET. ATTENTION: If booting an
* OS, the display driver must disable
* the hardware register of the graphic
* chip. Otherwise a blinking field is
* displayed.
