2007-05-08s3fb: driver fixesOndrej Zajicek
This fixes broken fbcon on Virge VX in 24 bpp mode, and contains several other small updates.

2007-05-08fbdev: save the activate field before calling fb_check_var()Antonino A. Daplas
Some drivers may reset the var->activate field on fb_check_var(). This can lead to undefined behavior. For example, doing fbset -a <option> with vga16fb will only modify the active console instead of modifying all.

2007-05-08fbcon: check if the character count can be handledAntonino A. Daplas
Fontmaps can be 256 or 512 in length. The only driver that can do tileblitting can only handle 256 characters. Check for this when setting the font.

2007-05-08fbdev: add tile operation to get the maximum length of the mapAntonino A. Daplas
Add a tile method, fb_get_tilemax(), that returns the maximum length of the tile map (or font map). This is needed by s3fb which can only handle 256 characters.

2007-05-08s3fb: limit 8x16 rectangles when tileblitting is enabledAntonino A. Daplas
If tileblitting is enabled (text mode), the hardware can only accept 8x16 bitmaps. Advertise this to the upper layer. And to ensure that an appropriate font is always available, select an 8x16 font in Kconfig.

2007-05-08fbcon: font setting should check limitation of driverAntonino A. Daplas
fbcon_set_font() will now check if the new font dimensions can be drawn by the driver (by checking pixmap.blit_x and blit_y). Similarly, add 2 new parameters to get_default_font(), font_w and font_h, to further aid in the font selection process.

2007-05-08fbdev: advertise limitation of drawing engineAntonino A. Daplas
A few drivers are not capable of blitting rectangles of any dimension. vga16fb can only blit 8-pixel wide rectangles, while s3fb (in tileblitting mode) can only blit 8x16 rectangles. For example, loading a 12x22 font in vga16fb will result in a corrupt display. Advertise this limitation/capability in info->pixmap.blit_x and blit_y. These fields are 32-bit arrays (font max is 32x32 only), ie, if bit 7 is set, then width/height of 7+1 is supported.

2007-05-08fbdev: add fb_read/fb_write functions for framebuffers in system RAMAntonino A. Daplas
The functions fb_read() and fb_write in fbmem.c assume that the framebuffer is in IO memory. However, we have 3 drivers (hecubafb, arcfb, and vfb) where the framebuffer is allocated from system RAM (via vmalloc). Using __raw_read/__raw_write (fb_readl/fb_writel) for these drivers is illegal, especially in other platforms. Create file read and write methods for these types of drivers. These are named fb_sys_read() and fb_sys_write().

2007-05-08fbdev: add drawing functions for framebuffers in system RAMAntonino A. Daplas
The generic drawing functions (cfbimgblt, cfbcopyarea, cfbfillrect) assume that the framebuffer is in IO memory. However, we have 3 drivers (hecubafb, arcfb, and vfb) where the framebuffer is allocated from system RAM (via vmalloc). Using _raw_read/write and family for these drivers (as used in the cfb* functions) is illegal, especially in other platforms. Create 3 new drawing functions, based almost entirely from the original except that the framebuffer memory is assumed to be in system RAM. These are named as sysimgblt, syscopyarea, and sysfillrect.

2007-05-08fbdev: don't show logo if driver or fbcon are modularAntonino A. Daplas
It was always intended for the logo to be drawn only if both fbcon and the driver that is mapped to it are both compiled statically. Currently, if fbcon is loaded prior to the driver, the logo is not shown. Reverse the order, and the code may attempt to draw the logo which is __initdata. By accident, this bug is rarely seen because this method of loading the modules is not common and secondly, a code in fb_prepare_logo() that checks the height of the logo (now a random value) rarely succeeds. Fix by drawing the logo only if both fbcon and the driver are statically compiled.
