// 2018-01-01 jDG:
//  - the exact address is fixed in linker script CPU1-F429.ld,
//    so that every font can be used even when not included in the actual
//    binary (boot-loader, fonts, or firmware).
//
//  - Actual font data is defined by the OSTC4/FontPack project, that shall
//    be loaded before the firmware is executed.
//
//  - Font directory starts at address 0x081E0000. Each header is 12 bytes.
//    A 0xFFFFFFFF (32 bits) marks the directory's end.
//    It is stored between __font_directory and __font_directory_end;
//
//  - Font data (chars) is stored after 0x08132040 (end of font's SFirmareData).
//    So there is space for 0x081E0000 - 0x08132040 = ADFC0 = 694 KB of fonts.
//    Actual data is stored between __upper_font_data and __upper_font_data_end,
//    and uses 0x081b9a3a - 0x08132040 = 879FA = 542 KB.
