2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

2018-08-09rk3288: Dig up two more KB of SRAM from under the couch cushionsJulius Werner
RK3288 has always been notoriously low on SRAM, to the point where its boards have less than 100 bytes left in both their bootblock/verstage sections. This becomes a problem every time we try to add a tiny amount of code to common coreboot interfaces that are included in them. This patch manages to add another KB to each, one from the CBMEM console (which now might get cut off a bit, but that's life) and one by moving the TTB_SUBTABLES to PMUSRAM. PMUSRAM is a weird world where write accesses must always be exactly 4 bytes long or they hang the CPU, so we mostly ignore it... but thankfully, page table entries are exactly 4 bytes long and that's the only thing we write to this region, so it works out in this case.

2018-05-22rk3399: Enable bootblock compressionJulius Werner
This patch enables the new bootblock compression feature on RK3399, which requires moving MMU initialization into the decompressor stage and linking the decompressor (rather than the bootblock) into the entry point jumped to by the masked ROM. RK3399's masked ROM seems to be using a bitbang SPI driver to load us (very long pauses between clocking in each byte), with an effective data rate of about 1Mbit. Bootblock loading time (as measured on a SPI analyzer) is reduced by almost 100ms (about a third), while the decompression time is trivial (under 1ms).

2018-04-03spi: Add helper functions for bit-bangingJulius Werner
Sometimes when bringing up a new board it can take a while until you have all the peripheral drivers ready. For those cases it is nice to be able to bitbang certain protocols so that you can already get further in the boot flow while those drivers are still being worked on. We already have this support for I2C, but it would be nice to have something for SPI as well, since without SPI you're not going to boot very far. This patch adds a couple of helper functions that platforms can use to implement bit-banging SPI with minimal effort. It also adds a proof of concept implementation using the RK3399.

2017-11-28rockchip/rk3399: mipi: properly configure PHY timingLin Huang
These values are specified as constant time periods but the PHY configuration is in terms of the current lane byte clock so using constant values guarantees that the timings will be outside the specification with some display configurations. Derive the necessary configuration from the byte clock in order to ensure that the PHY configuration is correct.

2017-11-28rockchip/rk3399: mipi: correct Feedback divider settingLin Huang
This patch correct Feedback divider setting: 1. Due to the use of a "by 2 pre-scaler," the range of the feedback multiplication Feedback divider is limited to even division numbers, and Feedback divider must be greater than 12, less than 1000. 2. Make the previously configured Feedback divider(LSB) factors effective Change-Id: Ic7c5c59be1d00c65c3b17cb3c4bfba8d7459e960 Signed-off-by: Lin Huang <hl@rock-chips.com> Reviewed-on: https://review.coreboot.org/22468 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>

2017-10-23soc: Add Kconfig for each soc vendorChris Ching
Allows explicit ordering for vendors that share a common configuration that must be sourced last. The issue is that chips in soc/{amd,intel}/[ab].* will be able to override defaults set in this file, but Kconfig files that get sourced later (soc/amd/[d-z].*) will NOT be able to override these defaults. Note: intel and amd soc chips now need to be added manually to the new Kconfig file BUG=b:62235314 TEST=make lint-stable Change-Id: Ida82ef184712e092aec1381a47aa1b54b74ed6b6 Signed-off-by: Chris Ching <chingcodes@google.com> Reviewed-on: https://review.coreboot.org/22123 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
2017-08-18include/device: Split i2c.h into threeNico Huber
Split `i2c.h` into three pieces to ease reuse of the generic defi- nitions. No code is changed. * `i2c.h` - keeps the generic definitions * `i2c_simple.h` - holds the current, limited to one controller driver per board, devicetree independent I2C interface * `i2c_bus.h` - will become the devicetree compatible interface for native I2C (e.g. non-SMBus) controllers Change-Id: I382d45c70f9314588663e1284f264f877469c74d Signed-off-by: Nico Huber <nico.huber@secunet.com> Reviewed-on: https://review.coreboot.org/20845 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
2017-08-14i2c: Move to Linux like `struct i2c_msg`Nico Huber
Our current struct for I2C segments `i2c_seg` was close to being compa- tible to the Linux version `i2c_msg`, close to being compatible to SMBus and close to being readable (e.g. what was `chip` supposed to mean?) but turned out to be hard to fix. Instead of extending it in a backwards compatible way (and not touching current controller drivers), replace it with a Linux source compatible `struct i2c_msg` and patch all the drivers and users with Coccinelle. The new `struct i2c_msg` should ease porting drivers from Linux and help to write SMBus compatible controller drivers. Beside integer type changes, the field `read` is replaced with a generic field `flags` and `chip` is renamed to `slave`. Patched with Coccinelle using the clumsy spatch below and some manual changes: * Nested struct initializers and one field access skipped by Coccinelle. * Removed assumption in the code that I2C_M_RD is 1. * In `i2c.h`, changed all occurences of `chip` to `slave`. @@ @@ -struct i2c_seg +struct i2c_msg @@ identifier msg; expression e; @@ ( struct i2c_msg msg = { - .read = 0, + .flags = 0, }; | struct i2c_msg msg = { - .read = 1, + .flags = I2C_M_RD, }; | struct i2c_msg msg = { - .chip = e, + .slave = e, }; ) @@ struct i2c_msg msg; statement S1, S2; @@ ( -if (msg.read) +if (msg.flags & I2C_M_RD) S1 else S2 | -if (msg.read) +if (msg.flags & I2C_M_RD) S1 ) @@ struct i2c_msg *msg; statement S1, S2; @@ ( -if (msg->read) +if (msg->flags & I2C_M_RD) S1 else S2 | -if (msg->read) +if (msg->flags & I2C_M_RD) S1 ) @@ struct i2c_msg msg; expression e; @@ ( -msg.read = 0; +msg.flags = 0; | -msg.read = 1; +msg.flags = I2C_M_RD; | -msg.read = e; +msg.flags = e ?
