15 help
16 System Control and Power Interface (SCPI) Message Protocol is
17 defined for the purpose of communication between the Application
18 Cores(AP) and the System Control Processor(SCP). The MHU peripheral
19 provides a mechanism for inter-processor communication between SCP
20 and AP.
21
22 SCP controls most of the power management on the Application
23 Processors. It offers control and management of: the core/cluster
24 power states, various power domain DVFS including the core/cluster,
25 certain system clocks configuration, thermal sensors and many
26 others.
27
28 This protocol library provides interface for all the client drivers
29 making use of the features offered by the SCP.

188 bool "Mark VGA/VBE/EFI FB as generic system framebuffer"
189 depends on X86 || EFI
190 select SYSFB
191 help
192 Firmwares often provide initial graphics framebuffers so the BIOS,
193 bootloader or kernel can show basic video-output during boot for
194 user-guidance and debugging. Historically, x86 used the VESA BIOS
195 Extensions and EFI-framebuffers for this, which are mostly limited
196 to x86 BIOS or EFI systems.
197 This option, if enabled, marks VGA/VBE/EFI framebuffers as generic
198 framebuffers so the new generic system-framebuffer drivers can be
199 used instead. If the framebuffer is not compatible with the generic
200 modes, it is advertised as fallback platform framebuffer so legacy
201 drivers like efifb, vesafb and uvesafb can pick it up.
202 If this option is not selected, all system framebuffers are always
203 marked as fallback platform framebuffers as usual.
204
205 Note: Legacy fbdev drivers, including vesafb, efifb, uvesafb, will
206 not be able to pick up generic system framebuffers if this option
207 is selected. You are highly encouraged to enable simplefb as
208 replacement if you select this option. simplefb can correctly deal
209 with generic system framebuffers. But you should still keep vesafb
210 and others enabled as fallback if a system framebuffer is
211 incompatible with simplefb.
212
213 If unsure, say Y.

233 help
234 Some devices (including most early Tegra-based consumer devices on
235 the market) are booted with the Trusted Foundations secure monitor
236 active, requiring some core operations to be performed by the secure
237 monitor instead of the kernel.
238
239 This option allows the kernel to invoke the secure monitor whenever
240 required on devices using Trusted Foundations. See the functions and
241 comments in linux/firmware/trusted_foundations.h or the device tree
242 bindings for "tlm,trusted-foundations" for details on how to use it.

51 device, it will become the console automatically. Otherwise,
52 you must specify the "console=hcdp" kernel boot argument.

55 so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
