+Entry: x86-reset16: x86 16-bit reset code for U-Boot
+----------------------------------------------------
+
+Properties / Entry arguments:
+    - filename: Filename of u-boot-x86-reset16.bin (default
+        'u-boot-x86-reset16.bin')
+
+x86 CPUs start up in 16-bit mode, even if they are 32-bit CPUs. This code
+must be placed at a particular address. This entry holds that code. It is
+typically placed at offset CONFIG_RESET_VEC_LOC. The code is responsible
+for jumping to the x86-start16 code, which continues execution.
+
+For 64-bit U-Boot, the 'x86_reset16_spl' entry type is used instead.
