2015-07-10Documentation: ARM: EXYNOS: Extend boot loader interface documentationKrzysztof Kozlowski
Extend the kernel-bootloader interface documentation with usage of register INFORM1 (0x0804) and different CPU resume address on Exynos542x family (with Multi-Cluster Power Management enabled). Additionally add glossary and reformat section titles. Signed-off-by: Krzysztof Kozlowski <k.kozlowski.k@gmail.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2015-06-08Documentation: ARM: EXYNOS: Describe boot loaders interfaceKrzysztof Kozlowski
Various boot loaders for Exynos based boards use certain memory addresses during booting for different purposes. Mostly this is one of following : 1. as a CPU boot address, 2. for storing magic cookie related to low power mode (AFTR, sleep). The document, based solely on kernel source code, tries to group the information scattered over different files. This would help in the future when adding support for new SoC or when extending features related to low power modes.
