The content of zh_TW was too outdated comparing to the original files.
Consequently carry out improvements in order to both keep track of sources
and fix several grammatical mistakes in traditional Chinese.
This is a thorough rewrite of the previous patch:
https://lore.kernel.org/linux-doc/20230807120006.6361-1-src.res.211@gmail.com/
in order to get rid of text damage and merging errors, created based on
linux-next (date: Oct. 9, 2023).

BMIPS設備樹引導
|
||
------------------------
|
||
|
||
一些bootloaders只支持在內核鏡像開始地址處的單一入口點。而其它
|
||
bootloaders將跳轉到ELF的開始地址處。兩種方案都支持的；因爲
|
||
CONFIG_BOOT_RAW=y and CONFIG_NO_EXCEPT_FILL=y, 所以第一條指令
|
||
會立即跳轉到kernel_entry()入口處執行。
|
||
|
||
與arch/arm情況(b)類似，dt感知的引導加載程序需要設置以下寄存器:
|
||
|
||
a0 : 0
|
||
|
||
a1 : 0xffffffff
|
||
|
||
a2 : RAM中指向設備樹塊的物理指針(在chapterII中定義)。
|
||
設備樹可以位於前512MB物理地址空間(0x00000000 -
|
||
0x1fffffff)的任何位置，以64位邊界對齊。
|
||
|
||
傳統bootloaders不會使用這樣的約定，並且它們不傳入DT塊。
|
||
在這種情況下，Linux將通過選中CONFIG_DT_*查找DTB。
|
||
|
||
以上約定只在32位系統中定義，因爲目前沒有任何64位的BMIPS實現。
