Hi joel,
I had sent you a rebased patch as a direct attachment, I will ping that

[PATCH] bsps/raspberrypi: Add SEV Instruction for RPi SMP firmware changes.

[pranav]

The Pi firmware added a wfe(wait for event), the cores 1-3 wait
for the start address being written to the mailbox register, followed
by a SEV poke to the mailbox that acts as a wfe wake-up event.

Re: [PATCH] bsps/raspberrypi: Add SEV instruction to Pi SMP

[Pranav Dangi]

The Pi firmware added a wfe(wait for event) so now, the cores 1-3 wait
for the start address being written to the mailbox register, followed
by a SEV that acts as a poke to the mailbox, or in other words, a wfe
wake-up event. I've added the SEV correspondingly here. So, would 'Add
SEV instruction' be the right way to say it? Or should I change the
subject.

Thanks,
pranav

Re: [PATCH rtems-docs 1/1] user/bsps/arm/raspberrypi: Changed the link to the Raspberry Pi Firmware to point to Firmware Version 1.20200601

[Pranav Dangi]

I tried debugging by adding printk() statements to the start-up code but
couldn't find anything conclusive. I am stuck there and am still trying to
figure out what broke the BSP after that particular version of the
firmware. If not, I will try to see if using u-boot we can fix this.
Meanwhile, this update to the docs temporarily ensures using of the older
firmware to boot the BSP.

Updated the link to the Raspberry Pi Firmware in RTEMS 5 docs, since the BSP 
works with an older version of the firmware currently.

GSoC'21 Raspberry Pi BSP project

[Pranav Dangi]

I've been going through the RTEMS raspberry pi repository, And i'm having
trouble understanding a couple of things there. the Pi1 (and Pi Zero) had
the BCM2835 SoC while the pi2 had the BCM2836 SoC, now, in the bsp
directory where the raspberry pi header is defined, the header file has
register definitions for both BCM2835 (for GPIO, I2C, etc.) and BCM2836
(for the 4 cores).
However, the corresponding i2c.c or gpio.c files for the bsp only have code
for the BCM2835_REG registers and not their BCM2836 i.e. the raspberry pi2
counterparts.
So, is the support for pi2 same as that of pi1 (selecting the particular
bsp doesn't make sense then) or am I missing something?
Since the Pi3 has the BCM2837 (the architecture of which is identical to
BC2836 since both are based on the BCM2709), any information about the
above would be helpful for me if I'm adding support for the Pi3 or 4 as my
GSoC project.

Re: GSoC 2021 - Raspberry Pi projects

[Pranav Dangi]

In addition to the previous mail, i've completed the basic Hello task. If a
mentor who has previously worked on the raspberry pi bsp could let me know
if the ticket is obsolete or not, I can immediately get started with the
required work on it.

GSoC 2021 - Raspberry Pi projects

[Pranav Dangi]

Hi everyone,
I am keen on working on the Raspberry Pi project #2899
. However, the ticket and also the
TODOs in the github README
 for the
same haven't been updated since 4 years, so I am not sure what work needs
to be done specifically. For example, the README lists support for SPI and
GPIO in TODO but apparently support for them has already been added.
Moreover given the smaller GSoC, I'd like a mentor to elaborate on the
potential scope of the project.
>From what I could understand so far, I think I can continue/complete the
previous GSoC projects(the situation seems fine on drivers for the initial
Pis), or work on the support for Pi 3 or 4.
PS: I only have spare Pi Zeroes at home, so I'll be getting the hardware
for the specific project this week depending on what aspect I have to work
on.
