-## Description
-
-This repository aims to provide an usable EDK2 UEFI environment for modern Qualcomm SoCs.
-
-It can be used as a boot manager for multi-booting mainline Linux, Android and optionally Windows on certain SoCs.

+# EDK2-MSM port for Xiaomi Poco F5 (SM7475 / Marble)
+
+This project aims to port EDK2-based UEFI firmware to the **Xiaomi Poco F5**, which is based on the **Snapdragon 7+ Gen 2 (SM7475)** SoC.  
+The port is based on prior support for SM8475 SoCs from the [EDK2-MSM](https://github.com/edk2-porting/edk2-msm) project.

+## Status
+
+| Component         | Status        |
+|------------------|----------------|
+| Firmware Build    | Successful   |
+| CoreDXE Boot      | Stable(?)    |
+| UART Output       | Not working  |
+| Display Output    | Black screen |
+| USB Debug (Gadget)| Not tested   |
+| Vibration Output  | Not tested   |

+
+## What Has Been Done
+
+### 1. Platform Bring-up
+- Cloned and renamed SM8475 support to `Platform/Xiaomi/sm7475/`.
+- Renamed and configured `.dsc`, `.fdf`, `.dec`, and other files for `sm7475` & `marble`.
+
+### 2. `.dsc` Configuration
+- Updated:
+  - `PcdSystemMemorySize` to match actual RAM.
+  - `PcdCoreCount`, `PcdClusterCount` using `cpuinfo`.
+  - Memory base addresses using `iomem`.
+- Added:
+  - `SerialPortLib` → `QcomGeniSerialPortLib`
+  - UART base address: `0x894000` 
+
+### 3. Apriori Drivers
+Manually extracted and included crucial DXE drivers:
+- `SmemDxe`, `DalSysDxe`, `HwIODxe`
+- `ChipInfoDxe`, `ClockDxe`, `PMICDxe`, `PlatformInfoDxe`, etc.
+
+### 4. Platform Library Modifications (`Silicon/Qualcomm/sm7475/Library/`)
+- **PlatformMemoryMapLib**:
+  - Adjusted MMIO/heap regions to avoid memory violations.
+- **PlatformPrePiLib**:
+  - Confirmed UART initialization is in place.
+- **marble.dec**:
+  - Added:
+    ```ini
+    gEfiMdePkgTokenSpaceGuid.PcdUartBaseAddress|UINT32|0x894000|0
+    ```
+### Planned Next Steps
+Test USB Gadget Console:
+
+    Enable ConfigFS or g_serial from firmware (if possible).
+
+    Attempt to log using dmesg | grep usb or detect /dev/ttyGS0.
