| 2 | hex "Address in memory or XIP flash of bootloader entry point" |
| 3 | help |
| 4 | After any reset, the boot ROM on the AM43XX SOC |
| 5 | searches the boot media for a valid boot image. |
| 6 | For non-XIP devices, the ROM then copies the |
| 7 | image into internal memory. |
| 8 | For all boot modes, after the ROM processes the |
| 9 | boot image it eventually computes the entry |
| 10 | point address depending on the device type |
| 11 | (secure/non-secure), boot media (xip/non-xip) and |
| 12 | image headers. |

| 15 | config PUB_ROM_DATA_SIZE |
| 16 | hex "Size in bytes of the L3 SRAM reserved by ROM to store data" |
| 17 | help |
| 18 | During the device boot, the public ROM uses the top of |
| 19 | the public L3 OCMC RAM to store r/w data like stack, |
| 20 | heap, globals etc. When the ROM is copying the boot |
| 21 | image from the boot media into memory, the image must |
| 22 | not spill over into this area. This value can be used |
| 23 | during compile time to determine the maximum size of a |
| 24 | boot image. Once the ROM transfers control to the boot |
| 25 | image, this area is no longer used, and can be reclaimed |
| 26 | for run time use by the boot image. |
