The first important part is the Memory Reference Code (MRC) +parameters. Quark MRC supports memory-down configuration only. All these MRC +parameters are supplied via the board device tree. To get started, first copy +the MRC section of arch/x86/dts/galileo.dts to your board's device tree, then +change these values by consulting board manuals or your hardware vendor. +Available MRC parameter values are listed in include/dt-bindings/mrc/quark.h. +The other tricky part is with PCIe. Quark SoC integrates two PCIe root ports, +but by default they are held in reset after power on. In U-Boot, PCIe +initialization is properly handled as per Quark's firmware writer guide. +In your board support codes, you need provide two routines to aid PCIe +initialization, which are board_assert_perst() and board_deassert_perst(). +The two routines need implement a board-specific mechanism to assert/deassert +PCIe PERST# pin. Care must be taken that in those routines that any APIs that +may trigger PCI enumeration process are strictly forbidden, as any access to +PCIe root port's configuration registers will cause system hang while it is +held in reset. For more details, check how they are implemented by the Intel +Galileo board support codes in board/intel/galileo/galileo.c. + TODO List --------- - Audio - Chrome OS verified boot - SMI and ACPI support, to provide platform info and facilities to Linux +- Desktop Management Interface (DMI) [15] support References ---------- @@ -755,3 +780,4 @@ References [12] http://events.linuxfoundation.org/sites/events/files/slides/chromeos_and_diy_vboot_0.pdf [13] http://events.linuxfoundation.org/sites/events/files/slides/elce-2014.pdf [14] doc/device-tree-bindings/misc/intel,irq-router.txt +[15] http://en.wikipedia.org/wiki/Desktop_Management_Interface diff --git a/doc/git-mailrc b/doc/git-mailrc index 598bb3e..6fe78a1 100644 --- a/doc/git-mailrc +++ b/doc/git-mailrc @@ -12,6 +12,7 @@ alias u-boot uboot # things simple and easy to look up/coordinate. alias aaribaud Albert Aribaud <albert.u.boot@aribaud.net> alias abiessmann Andreas Bießmann <andreas.devel@googlemail.com> +alias abrodkin Alexey Brodkin <alexey.brodkin@synopsys.com> alias afleming Andy Fleming <afleming@gmail.com> alias ag Anatolij Gustschin <agust@denx.de> alias alisonwang Alison Wang <alison.wang@freescale.com> @@ -50,9 +51,11 @@ alias vapier Mike Frysinger <vapier@gentoo.org> alias wd Wolfgang Denk <wd@denx.de> # Architecture aliases -alias arch arm, avr32, bfin, m68k, microblaze, mips, nds32, nios2, powerpc, sandbox, superh, sparc, x86 +alias arch arc, arm, avr32, bfin, m68k, microblaze, mips, nds32, nios2, powerpc, sandbox, superh, sparc, x86 alias arches arch +alias arc uboot, abrodkin + alias arm uboot, aaribaud alias at91 uboot, abiessmann alias davinci ti |
