| * The RTC internal registers and RAM is organized as two banks of 128 bytes |
| * each, called the standard and extended banks. The first 14 bytes of the |
| * standard bank contain the RTC time and date information along with four |
| * registers, A - D, that are used for configuration of the RTC. The extended |
| * bank contains a full 128 bytes of battery backed SRAM. |
| * For simplicity in U-Boot we only support CMOS in the standard bank, and |
| * its base address starts from offset 0x10, which leaves us 112 bytes space. |
| * The file records all offsets off CMOS_BASE that is currently used by |
| * U-Boot for various reasons. It is put in such a unified place in order |
| * to be consistent across platforms. |
