Rename Bootrom pages
I would like to rename the bootrom pages from iBoot-xxx to something different, because of two reasons:
- The same name format is currently being used for iBoot stage 2 bootloader pages, which causes confusion.
- The bootrom for the S5L8900 has no version number, as IH8sn0w just pointed out. It just shows
Apple Computer, Inc. USB DFU Device 89000000000001 S5L8900 Rev.2 ROM BOOT
in the code.
I would suggest a new name starting with "Bootrom" and then either the application processor name (like S5Lxxxx) together with a version (like A, B, or old, new) or the version number like "Bootrom 838.1" and a special name for the 8900, like "Bootrom S5L8900". Personally I would prefer the processor named version, but I don't like the old/new or A/B in it. Maybe just add the version where it's known? So finally I would suggest these names:
- Bootrom S5L8900 Rev.2
- Bootrom S5L8720 240.4
- Bootrom S5L8720 240.5.1
- Bootrom S5L8920 359.3
- Bootrom S5L8920 359.3.2
- Bootrom S5L8922 359.5
- Bootrom S5L8930 574.4

- I don't think mentioning the CPU in the page title is necessary. (It'd definitely be acknowledged in the bootrom's page anyways.) I like the sound of Bootrom Rev.2, Bootrom 240.4, etc. --Dialexio 10:01, 7 March 2012 (MST)
- I don't like 'SecureROM' too much, because it's more a product name and could change, while 'Bootrom' is more neutral. Also, if I hear 'SecureROM', immediately planetbeing's "it's not so secure" (from 25C3) comes to my mind. Also the "SecureBoot" sounds very similar. But if others like it, that's fine for me too. But for the rest of the name? Is my last suggestion there ok? --http 00:43, 7 March 2012 (MST)
