The Linux 15 * logo can be placed in the upper left corner and additional board 16 * information strings (that normally goes to serial port) can be drawn. 17 * 18 * The console driver can use a keyboard interface for character input 19 * but this is deprecated. Only rk51 uses it. 20 * 21 * Character output goes to a memory-mapped video 22 * framebuffer with little or big-endian organisation. 23 * With environment setting 'console=serial' the console i/o can be 24 * forced to serial port. 25 * 26 * The driver uses graphic specific defines/parameters/functions: 27 * 28 * (for SMI LynxE graphic chip) 29 * 30 * CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810 31 * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian 32 * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill 33 * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt 34 * 35 * Console Parameters are set by graphic drivers global struct: 36 * 37 * VIDEO_VISIBLE_COLS - x resolution 38 * VIDEO_VISIBLE_ROWS - y resolution 39 * VIDEO_PIXEL_SIZE - storage size in byte per pixel 40 * VIDEO_DATA_FORMAT - graphical data format GDF 41 * VIDEO_FB_ADRS - start of video memory 42 * 43 * VIDEO_KBD_INIT_FCT - init function for keyboard 44 * VIDEO_TSTC_FCT - keyboard_tstc function 45 * VIDEO_GETC_FCT - keyboard_getc function 46 * 47 * CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner. 48 * Use CONFIG_SPLASH_SCREEN_ALIGN with 49 * environment variable "splashpos" to place 50 * the logo on other position. In this case 51 * no CONSOLE_EXTRA_INFO is possible. 52 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 53 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information 54 * strings that normaly goes to serial 55 * port. This define requires a board 56 * specific function: 57 * video_drawstring (VIDEO_INFO_X, 58 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 59 * info); 60 * that fills a info buffer at i=row. 61 * s.a: board/eltec/bab7xx. 62 * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be 63 * initialized as an output only device. 64 * The Keyboard driver will not be 65 * set-up. This may be used, if you have 66 * no or more than one Keyboard devices 67 * (USB Keyboard, AT Keyboard). 68 * 69 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 70 * character. No blinking is provided. 71 * Uses the macros CURSOR_SET and 72 * CURSOR_OFF. 73 * 74 * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability 75 * of the graphic chip. Uses the macro 76 * CURSOR_SET. ATTENTION: If booting an 77 * OS, the display driver must disable 78 * the hardware register of the graphic 79 * chip. Otherwise a blinking field is 80 * displayed. 81 */ 82 83 #include <common.h> 84 #include <fdtdec.h> 85 #include <version.h> 86 #include <malloc.h> 87 #include <linux/compiler.h> 88 89 /* 90 * Console device defines with SMI graphic 91 * Any other graphic must change this section 92 */ 93 94 #ifdef CONFIG_VIDEO_SMI_LYNXEM 95 96 #define VIDEO_FB_LITTLE_ENDIAN 97 #define VIDEO_HW_RECTFILL 98 #define VIDEO_HW_BITBLT 99 #endif 100 101 /* 102 * Defines for the CT69000 driver 103 */ 104 #ifdef CONFIG_VIDEO_CT69000 105 106 #define VIDEO_FB_LITTLE_ENDIAN 107 #define VIDEO_HW_RECTFILL 108 #define VIDEO_HW_BITBLT 109 #endif 110 111 /* 112 * Defines for the SED13806 driver 113 */ 114 #ifdef CONFIG_VIDEO_SED13806 115 #define VIDEO_FB_LITTLE_ENDIAN 116 #define VIDEO_HW_RECTFILL 117 #define VIDEO_HW_BITBLT 118 #endif 119 120 #if defined(CONFIG_VIDEO_MXS) || defined(CONFIG_VIDEO_S3C) 121 #define VIDEO_FB_16BPP_WORD_SWAP 122 #endif 123 124 /* 125 * Defines for the MB862xx driver 126 */ 127 #ifdef CONFIG_VIDEO_MB862xx 128 129 #ifdef CONFIG_VIDEO_CORALP 130 #define VIDEO_FB_LITTLE_ENDIAN 131 #endif 132 #ifdef CONFIG_VIDEO_MB862xx_ACCEL 133 #define VIDEO_HW_RECTFILL 134 #define VIDEO_HW_BITBLT 135 #endif 136 #endif 137 138 /* 139 * Defines for the i.MX31 driver (mx3fb.c) 140 */ 141 #if defined(CONFIG_VIDEO_MX3) || defined(CONFIG_VIDEO_IPUV3) 142 #define VIDEO_FB_16BPP_WORD_SWAP 143 #endif 144 145 /* 146 * Include video_fb.h after definitions of VIDEO_HW_RECTFILL etc. 147 */ 148 #include <video_fb.h> 149 150 #include <splash.h> 151 152 /* 153 * some Macros 154 */ 155 #define VIDEO_VISIBLE_COLS (pGD->winSizeX) 156 #define VIDEO_VISIBLE_ROWS (pGD->winSizeY) 157 #define VIDEO_PIXEL_SIZE (pGD->gdfBytesPP) 158 #define VIDEO_DATA_FORMAT (pGD->gdfIndex) 159 #define VIDEO_FB_ADRS (pGD->frameAdrs) 160 161 /* 162 * Console device 163 */ 164 165 #include <version.h> 166 #include <linux/types.h> 167 #include <stdio_dev.h> 168 #include <video_font.h> 169 170 #if defined(CONFIG_CMD_DATE) 171 #include <rtc.h> 172 #endif 173 174 #if defined(CONFIG_CMD_BMP) || defined(CONFIG_SPLASH_SCREEN) 175 #include <watchdog.h> 176 #include <bmp_layout.h> 177 #include <splash.h> 178 #endif 179 180 /* 181 * Cursor definition: 182 * CONFIG_VIDEO_SW_CURSOR: Draws a cursor after the last character.
