34 | Xtensa processors are 32-bit RISC machines designed by Tensilica | |
35 | primarily for embedded systems. These processors are both | |
36 | configurable and extensible. The Linux port to the Xtensa | |
37 | architecture supports all processor configurations and extensions, | |
38 | with reasonable minimum requirements. The Xtensa Linux project has | |
0ada4490 | 39 | a home page at <http://www.linux-xtensa.org/>. |

220 | Earlier version initialized the MMU in the exception vector | |
221 | before jumping to _startup in head.S and had an advantage that | |
222 | it was possible to place a software breakpoint at 'reset' and | |
223 | then enter your normal kernel breakpoints once the MMU was mapped | |
224 | to the kernel mappings (0XC0000000). | |
225 | ||
226 | This unfortunately doesn't work for U-Boot and likley also wont | |
227 | work for using KEXEC to have a hot kernel ready for doing a | |
228 | KDUMP. | |
229 | ||
230 | So now the MMU is initialized in head.S but it's necessary to | |
231 | use hardware breakpoints (gdb 'hbreak' cmd) to break at _startup. | |
232 | xt-gdb can't place a Software Breakpoint in the 0XD region prior | |
233 | to mapping the MMU and after mapping even if the area of low memory | |
234 | was mapped gdb wouldn't remove the breakpoint on hitting it as the | |
235 | PC wouldn't match. Since Hardware Breakpoints are recommended for | |
236 | Linux configurations it seems reasonable to just assume they exist | |
237 | and leave this older mechanism for unfortunate souls that choose | |
238 | not to follow Tensilica's recommendation. | |
239 | ||

432 | help | |
433 | On some architectures (EBSA110 and CATS), there is currently no way | |
434 | for the boot loader to pass arguments to the kernel. For these | |
435 | architectures, you should supply some command-line options at build | |
436 | time by entering them here. As a minimum, you should specify the | |
437 | memory size and the root device (e.g., mem=64M root=/dev/nfs). | |

492 | help | |
493 | The kernel memory allocator divides physically contiguous memory | |
494 | blocks into "zones", where each zone is a power of two number of | |
495 | pages. This option selects the largest power of two that the kernel | |
496 | keeps in the memory allocator. If you need to allocate very large | |
497 | blocks of physically contiguous memory, then you may need to | |
498 | increase this value. | |
499 | ||
500 | This config option is actually maximum order plus one. For example, | |
501 | a value of 11 means that the largest free memory block is 2^10 pages. | |
