+//  - 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.
