| hex "Default framebuffer size to use if no drivers request it" |
| default 0x1000000 if X86 && PCI |
| default 0 if !(X86 && PCI) |
| help |
| Generally, video drivers request the amount of memory they need for |
| the frame buffer when they are bound, by setting the size field in |
| struct video_uc_plat. That memory is then reserved for use after |
| relocation. But PCI drivers cannot be bound before relocation unless |
| they are mentioned in the devicetree. |
| |
| With this value set appropriately, it is possible for PCI video |
| devices to have a framebuffer allocated by U-Boot. |
| |
| Note: the framebuffer needs to be large enough to store all pixels at |
| maximum resolution. For example, at 1920 x 1200 with 32 bits per |
| pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed. |
| |
| config VIDEO_COPY |
| bool "Enable copying the frame buffer to a hardware copy" |
| help |
| On some machines (e.g. x86), reading from the frame buffer is very |

| allows the frame buffer to be kept in cached memory (allocated by |
| U-Boot) and then copied to the hardware frame-buffer as needed. |
| |
| To use this, your video driver must set @copy_base in |
| struct video_uc_plat. |

| This sets the font size for the console. The size is measured in |
| pixels and is the nominal height of a character. Note that fonts |
| are commonly measured in 'points', being 1/72 inch (about 3.52mm). |
| However that measurement depends on the size of your display and |
| there is no standard display density. At present there is not a |
| method to select the display's physical size, which would allow |

| This sets the number of font / size combinations which can be used by |

| boot menus are in use, this may need to be increased. |
| |
| Note that a separate entry is needed for each font size, even if the |
