| 2 | Summary |
| 3 | ======= |
| 4 | |
| 5 | This README is about U-Boot support for TI's ARM Cortex-A8 based OMAP3 [1] |
| 6 | family of SoCs. TI's OMAP3 SoC family contains an ARM Cortex-A8. Additionally, |
| 7 | some family members contain a TMS320C64x+ DSP and/or an Imagination SGX 2D/3D |
| 8 | graphics processor and various other standard peripherals. |
| 9 | |
| 10 | Currently the following boards are supported: |
| 11 | |
| 12 | * OMAP3530 BeagleBoard [2] |

| 25 | ========= |
| 26 | |
| 27 | While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile |
| 28 | with -march=armv5 to allow more compilers to work. For U-Boot code this has |
| 29 | no performance impact. |

Dirk Behme | f904cdb | 2009-01-27 18:19:12 +0100 | [diff] [blame] | 64 | Custom commands |
| 65 | =============== |
| 66 | |
| 67 | To make U-Boot for OMAP3 support NAND device SW or HW ECC calculation, U-Boot |
| 68 | for OMAP3 supports custom user command |
| 69 | |
| 70 | nandecc hw/sw |
| 71 | |
| 72 | To be compatible with NAND drivers using SW ECC (e.g. kernel code) |
| 73 | |
| 74 | nandecc sw |
| 75 | |
| 76 | enables SW ECC calculation. HW ECC enabled with |
| 77 | |
| 78 | nandecc hw |
| 79 | |
| 80 | is typically used to write 2nd stage bootloader (known as 'x-loader') which is |
| 81 | executed by OMAP3's boot rom and therefore has to be written with HW ECC. |
| 82 | |
